Precision, Quad, SPST Analog Switches
General Description
The MAX391/MAX392/MAX393 are precision, quad, single-pole/single-throw (SPST) analog switches designed to operate at +3V, +5V, or 5V. The MAX391 has four normally closed (NC) switches, and the MAX392 has four normally open (NO) switches. The MAX393 has two NO and two NC switches. All three devices offer low leakage (100pA max) and fast switching speeds (tON 130ns, tOFF 75ns). Power consumption is just 1W--ideal for battery-operated equipment. All devices operate from a single +3V to +15V supply or from dual 3.0V to 8V supplies. With 5V supplies, the MAX391/MAX392/MAX393 offer guaranteed 2 max channel-to-channel matching, 30 max on-resistance (RON), and 4 max RON flatness over the specified range. These switches are also fully specified for single +5V operation, with 2 max RON match, 60 max RON, and 6 max flatness. These low-voltage switches also offer 5pC max charge injection, and ESD protection is greater than 2000V, per method 3015.7.

Note 1:
Signals on NC, NO, COM, or IN exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to maximum current rating.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet. Guaranteed by design. RON = RON max - RON min. Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal range. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25C. Off Isolation = 20log10 [ VCOM (VNC or VNO) ], VCOM = output, VNC or VNO = input to off switch. Between any two switches. Leakage testing at single supply is guaranteed by testing with dual singles.

__________Applications Information
Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings may cause permanent damage to the devices. Always sequence V+ on first, followed by V-, and then logic inputs. If power-supply sequencing is not possible, add two small signal diodes in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range to 1V below V+ and 1V below V-, but low switch resistance and low leakage characteristics are unaffected. Device operation is unchanged, and the difference between V+ and V- should not exceed 17V.
