双路单刀单掷模拟开关 Dual single-pole single-throw analog switch
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.
