1. General description

The 74HC2G66-Q100; 74HCT2G66-Q100 is a dual single pole, single-throw analog switch. Each

switch has two input/output terminals (nY and nZ) and a digital enable input (nE). When nE is LOW,

the analog switch is turned off. Inputs include clamp diodes that enable the use of current limiting

resistors to interface inputs to voltages in excess of VCC.

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

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