Datasheet

1. General description
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.
2. Features and benefits
