FUNCTION

Switch Input Terminals. Drive ≤ 0.8V for logic “0”; drive ≥ 5V for logic “1”.

Analog Switch Common Terminal

Switch Inputs

Negative Supply Voltage Input. Normally connected to ground.

Ground

No Connection. Not internally connected.

Positive Supply Voltage Input. Connected to substrate.

__________Applications Information

Overvoltage Protection

Proper power-supply sequencing is recommended for

all CMOS devices. Do not exceed the absolute maxi-

mum ratings because stresses beyond the listed rat-

ings may cause permanent damage to the devices.

Always sequence V+ on first, followed by the logic

inputs. If power-supply sequencing is not possible, add

a small signal diode in series with V+ for overvoltage

protection (Figure 1). Adding a diode reduces the ana-

log signal range to 1V below V+, but low switch resis-

tance and low leakage characteristics are unaffected.

Device operation is unchanged, and the difference

between V+ and V- should not exceed 17V.
