1. General description

The 74AHC1G66-Q100; 74AHCT1G66-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. The enable input is overvoltage tolerant. This feature allows the use of these

devices as translators in mixed voltage environments.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
