Single-pole single-throw analog switch
Rev. 1 — 16 September 2013
Product data sheet
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.

To avoid drawing V
CC
current from pin Z, when switch current flows in pin Y, the voltage drop across the bidirectional switch must not
exceed 0.4 V. If the switch current flows into pin Z, no V
CC
current flows from terminal Y. In this case, the voltage drop across the switch
is unlimited, but the voltage at pins Y and Z may not exceed V
CC
or GND.
