1. General description
The 74LVC1G66-Q100 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.
