The device features two inverting and two noninverting open-collector outputs with a common-enable input that, when taken high, disables all four outputs. By pairing each inverting channel with a corresponding noninverting channel (such as channel 1 paired with channel 2 and channel 3 paired with channel 4), the device may be used as a complete full-step 4-phase dc stepper-motor driver using only two input logic control signals plus the enable signal, as shown in Figure 3. Other applications include driving relays, lamps, solenoids, motors, LEDs, transmission lines, hammers, and other high-power-demand loads. The SN75439 is characterized for operation from 0C to 70C. 3A 10 4A 9 8 7 4Y 3, 4D This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC publication 617-12.

All voltage values are with respect to the network GND (unless otherwise specified). 2. All four channels of this device may conduct rated current simultaneously; however, power dissipation average over a short time interval must fall within the continuous dissipation range. 3. For operation above 25C free-air temperature, derate linearly at the rate of 16.6 mW/C. For operation above 65C case temperature, derate linearly at the rate of 59 mW/C. To avoid exceeding the design maximum virtual junction temperature, these ratings should not be exceeded. 3-2 POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 SN75439 QUADRUPLE PERIPHERAL DRIVER SLRS013A - MAY 1988 - REVISED NOVEMBER 1989 recommended operating conditions MIN Supply voltage, VCC Output supply voltage in inductive switching circuit, VS (see Figure 2) High-level input voltage, VIH Low-level input voltage, VIL Low-level output current, IOL 2 - 0.3 4.75 NOM 5 MAX 5.25 40 5.25 0.8 1.3 UNIT V V V V A Operating free-air temperature, TA 0 25 70 C The algebraic convention, in which the least positive (most negative) value is designated minimum, is used in this data sheet for logic voltage levels. electrical characteristics over recommended ranges of operating free-air temperature and supply voltages (unless otherwise noted) PARAMETER VIK VOL Input clamp voltage Low-level output voltage TEST CONDITIONS II = - 12 mA IOL = 0.5 A IOL = 1 A IOL = 1.3 A IF = 0.5 A IF = 1 A IF = 1.3 A VOH = 50 V, VI = VIH VI = 0 to 0.8 V VR = 50 V, VO = 0 All outputs at high level (off) All outputs at low level (on) Two outputs at high level (off) and two outputs at low level (on) 2 140 70 See Note 4 MIN TYP - 0.9 0.2 0.4 0.5 1.1 See Note 4 VOK = 50 V 1.3 1.4 MAX - 1.5 0.35 0.7 0.9 1.9 2.2 2.4 100 10 - 10 100 8 200 110 mA A A A A V V UNIT V VF(K) () IOH IIH IIL IR(K) Output clamp-diode forward voltage High-level output current High-level input current Low-level input current Output clamp-diode reverse current (at Y output) ICC Su ly Supply current All typical values are at VCC = 5 V, TA = 25C.
