Applications Information
Positive Supply
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, and then logic inputs.
If power-supply sequencing is not possible, add two small signal
diodes or two current limiting resistors in series with the supply
pins for overvoltage protection (Figure 1). Adding diodes reduces
the analog signal range, but low switch resistance and low leakage
characteristics are unaffected.
Logic Levels
When powered from +5V the PS301/PS302/PS303 can be oper-
ated with either TTL- or CMOS-Logic levels. If V+ is different
than +5V, the logic threshold level will vary.
Power consumption is minimal when the logic control voltages
reach V+ or GND.

Figure 1. Overvoltage protection is accomplished by using two
external blocking diodes or two current limiting resistors.
