adum140x digital isolator requires no external interface circuitry for the logic interfaces. power supply bypassing is strongly recommended at the input and output supply pins (see figure 17 ). bypass capacitors are most conveniently connected between pin 1 and pin 2 for v dd1 and between pin 15 and pin 16 for v dd2 . the capacitor value should be between 0.01 f and 0.1 f. the total lead length between both ends of the capacitor and the input power supply pin should not exceed 20 mm. bypassing between pin 1 and pin 8 and between pin 9 and pin 16 should also be considered, unless the ground pair on each package side is connected close to the package. v dd1 gnd 1 v ia v ib v ic /v oc v id/ v od nc/v e1 gnd 1 v dd2 gnd 2 v oa v ob v oc/ v ic v od/ v id v e2 gnd 2 0 3786-017 figure 17. recommended printed circuit board layout in applications involving high common-mode transients, care should be taken to ensure that board coupling across the isolation barrier is minimized. furthermore, the board layout should be designed such that any coupling that does occur equally affects all pins on a given component side. failure to ensure this could cause voltage differentials between pins exceeding the absolute maximum ratings of the device, thereby leading to latch-up or permanent damage. propagation delay-related parameters propagation delay is a parameter that describes the time it takes a logic signal to propagate through a component. the propagation delay to a logic 0 output may differ from the propagation delay to a logic 1 output. input ( v ix ) output (v ox ) t plh t phl 50% 50% 03786-018 figure 18. propagation delay parameters pulse width distortion is the maximum difference between these two propagation delay values and is an indication of how accurately the timing of the input signal is preserved. channel-to-channel matching refers to the maximum amount the propagation delay differs between channels within a single adum140x component. propagation delay skew refers to the maximum amount the propagation delay differs between multiple adum140x components operating under the same conditions. dc correctness and magnetic field immunity positive and negative logic transitions at the isolator input cause narrow (~1 ns) pulses to be sent to the decoder via the transformer. the decoder is bistable and is, therefore, either set or reset by the pulses, indicating input logic transitions. in the absence of logic transitions at the input for more than ~1 s, a periodic set of refresh pulses indicative of the correct input state are sent to ensure dc correctness at the output. if the decoder receives no internal pulses of more than about 5 s, the input side is assumed to be unpowered or nonfunctional, in which case the isolator output is forced to a default state (see table 1 5 ) by the watchdog timer circuit. the limitation on the magnetic field immunity of the adum140x is set by the condition in which induced voltage in the receiving coil of the transformer is sufficiently large enough to either falsely set or reset the decoder. the following analysis defines the conditions under which this may occur. the 3 v operating condition of the adum140x is examined because it represents the most susceptible mode of operation. the pulses at the transformer output have an amplitude greater than 1.0 v. the decoder has a sensing threshold at about 0.5 v, thus establishing a 0.5 v margin in which induced voltages can be tolerated. the voltage induced across the receiving coil is given by v = ( ?d/dt ) r n 2 ; n = 1, 2, , n where: is magnetic flux density (gauss). n is the number of turns in the receiving coil. r n is the radius of the n th turn in the receiving coil (cm). given the geometry of the receiving coil in the adum140x and an imposed requirement that the induced voltage be 50% at most of the 0.5 v margin at the decoder, a maximum allowable magnetic field is calculated as shown in figure 19 . magnetic field frequency (hz) 100 maximum allowable magnetic flux density (kgauss) 0.001 1m 10 0.01 1k 10k 10m 0.1 1 100m 100k 03786-019 figure 19. maximum allowable external magnetic flux density adum1400/adum1401/adum1402 rev. g | page 28 of 32 for example, at a magnetic field frequency of 1 mhz, the maximum allowable magnetic field of 0.2 kgauss induces a voltage of 0.25 v at the receiving coil. this is about 50% of the sensing threshold and does not cause a faulty output transition. similarly, if such an event occurs during a transmitted pulse (and has the worst-case polarity), it reduces the received pulse from >1.0 v to 0.75 vstill well above the 0.5 v sensing threshold of the decoder. the preceding magnetic flux density values correspond to specific current magnitudes at given distances from the adum140x transformers. figure 20 expresses these allowable current magnitudes as a function of frequency for selected distances. as shown, the adum140x is extremely immune and can be affected only by extremely large currents operated at high frequency very close to the component. for the 1 mhz example noted, one would have to place a 0.5 ka current 5 mm away from the adum140x to affect the operation of the component. magnetic field frequency (hz) maximum allowable current (ka) 1000 100 10 1 0.1 0.01 1k 10k 100m 100k 1m 10m distance = 5mm distance = 1m distance =

board traces could induce error voltages sufficiently large enough to trigger the thresholds of succeeding circuitry. care should be taken in the layout of such traces to avoid this possibility. power consumption the supply current at a given channel of the adum140x isolator is a function of the supply voltage, the data rate of the channel, and the output load of the channel. for each input channel, the supply current is given by i ddi = i ddi ( q ) f 0.5 f r i ddi = i ddi (d) (2 f ? f r ) + i ddi ( q ) f > 0.5 f r for each output channel, the supply current is given by i ddo = i ddo ( q ) f 0.5 f r i ddo = ( i ddo ( d ) + (0.5 10 ?3 ) c l v ddo ) (2 f ? f r ) + i ddo ( q ) f > 0.5 f r where: i ddi (d) , i ddo (d) are the input and output dynamic supply currents per channel (ma/mbps). c l is the output load capacitance (pf). v ddo is the output supply voltage (v). f is the input logic signal frequency (mhz); it is half of the input data rate expressed in units of mbps. f r is the input stage refresh rate (mbps). i ddi (q) , i ddo (q) are the specified input and output quiescent supply currents (ma). to calculate the total v dd1 and v dd2 supply current, the supply currents for each input and output channel corresponding to v dd1 and v dd2 are calculated and totaled. figure 8 and figure 9 provide per-channel supply currents as a function of data rate for an unloaded output condition. figure 10 provides per- channel supply current as a function of data rate for a 15 pf output condition. figure 11 through figure 15 provide total v dd1 and v dd2 supply current as a function of data rate for adum1400/adum1401/adum1402 channel configurations. adum1400/adum1401/adum1402 rev. g | page 29 of 32 insulation lifetime all insulation structures eventually break down when subjected to voltage stress over a sufficiently long period. the rate of insulation degradation is dependent on the characteristics of the voltage waveform applied across the insulation. in addition to the testing performed by the regulatory agencies, analog devices carries out an extensive set of evaluations to determine the lifetime of the insulation structure within the adum140x. analog devices performs accelerated life testing using voltage levels higher than the rated continuous working voltage. accel- eration factors for several operating conditions are determined. these factors allow calculation of the time to failure at the actual working voltage. the values shown in table 14 summarize the peak voltage for 50 years of service life for a bipolar ac operating condition and the maximum csa/vde approved working voltages. in many cases, the approved working voltage is higher than a 50-year service life voltage. operation at these high working voltages can lead to shortened insulation life in some cases. the insulation lifetime of the adum140x depends on the voltage waveform type imposed across the isolation barrier. the i coupler insulation structure degrades at different rates depending on whether the waveform is bipolar ac, unipolar ac, or dc. figure 21 , figure 22 , and figure 23 illustrate these different isolation voltage waveforms, respectively. bipolar ac voltage is the most stringent environment. the goal of a 50-year operating lifetime under the ac bipolar condition determines the analog devices recommended maximum working voltage. in the case of unipolar ac or dc voltage, the stress on the insulation is significantly lower, which allows operation at higher working voltages while still achieving a 50-year service life. the working voltages listed in table 14 can be applied while maintaining the 50-year minimum lifetime, provided the voltage conforms to either the unipolar ac or dc voltage cases. any cross- insulation voltage waveform that does not conform to figure 22 or figure 23 should be treated as a bipolar ac waveform, and its peak voltage should be limited to the 50-year lifetime voltage value listed in table 14 . note that the voltage presented in figure 22 is shown as sinusoidal for illustration purposes only. it is meant to represent any voltage waveform varying between 0 v and some limiting value. the limiting value can be positive or negative, but the voltage cannot cross 0 v. 0v rated peak voltage 03786-021 figure 21. bipolar ac waveform 0v rated peak voltage 03786-022 figure 22. unipolar ac waveform 0v rated
