1. General description

The 74LVCV2G66 is a low-power, low-voltage, high-speed Si-gate CMOS device.

The 74LVCV2G66 provides two single pole single throw analog or digital switches. Each switch

includes an overvoltage tolerant input/output terminal (pin nZ), an output/input terminal (pin nY) and

low-power active HIGH enable input (pin nE).

The overvoltage tolerant switch terminals allow the switching of signals in excess of VCC. The

low-power enable input eliminates the necessity of using current limiting resistors in portable

applications when using control logic signals much lower than VCC. These inputs are also

overvoltage tolerant.
