1. General description
The 74LVC1G66 is a single-pole, single-throw analog switch with two input/output terminals (nY
and nZ) and a digital enable input (nE). When nE is LOW, the analog switch is turned off. Control
inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices
as translators in mixed 3.3 V and 5 V environments.
Schmitt-trigger action at control inputs makes the circuit tolerant of slower input rise and fall times.
