74HC2G66-Q100; 74HCT2G66-Q100
Dual single-pole single-throw analog switch
Rev. 2 6 November 2018 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 .
