Dual single-pole single-throw analog switch
Rev. 05 — 26 January 2009
Product data sheet
1. General description
74HC2G66 and 74HCT2G66 are high-speed Si-gate CMOS devices. They are dual
single-pole single-throw analog switches. Each switch has two input/output pins
(nY and nZ) and an active HIGH enable input pin (nE). When pin nE is LOW, the analog
switch is turned off.

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.
