Dual single-pole single-throw analog switch
Rev. 06 — 2 April 2010
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.
2. Features and benefits
