1. General description
The 74HC1G66-Q100; 74HCT1G66-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. Inputs include clamp diodes that enable the use of
current limiting resistors to interface inputs to voltages in excess of V
CC
.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
