Product data sheet
1. General description
The 74LVC1G66 is a low-power, low-voltage Si-gate CMOS device.
The 74LVC1G66 provides one single pole, single-throw analog switch function. It has two
input/output terminals (Y and Z) and an active HIGH enable input pin (E). When E is LOW,
the analog switch is turned off.
Schmitt-trigger action at the enable input makes the circuit tolerant of slower input rise and
fall times across the entire V
CC
range from 1.65 V to 5.5 V.

To avoid sinking GND current from terminal Z when switch current flows in terminal Y, the voltage drop across the bidirectional switch
must not exceed 0.4 V. If the switch current flows into terminal Z, no GND current will flow from terminal Y. In this case, there is no limit
for the voltage drop across the switch.
Applies to control signal levels.
