Overvoltage tolerant bilateral switch

Product data sheet
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 V_CC.
The low-power enable input eliminates the necessity of using current limiting resistors in
portable applications when using control logic signals much lower than V_CC. These inputs
are also overvoltage tolerant.
