Dual single-pole single-throw analog switch
Rev. 1 — 18 November 2013
Product data sheet
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 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 out of pin nZ, when switch current flows in pin nY, the voltage drop across the bidirectional switch must not
exceed 0.4 V. If the switch current flows into pin nZ, no V
CC
current flows out of terminal nY. In this case, there is no limit for the voltage
drop across the switch, but the voltage at pins nY and nZ may not exceed V
CC
or GND.
