74HC2G66; 74HCT2G66
Rev. 11 — 6 November 2018
Dual single-pole single-throw analog switch
Product data sheet
1. General description
The 74HC2G66; 74HCT2G66 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. This enables the use of current limiting resistors
to interface inputs to voltages in excess of V
CC
.

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 will flow 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.
