74HC2G66GT中文资料安世数据手册PDF规格书

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 VCC.
