74LVCV2G66
Overvoltage tolerant bilateral switch
Rev. 01 — 2 April 2004
Product data sheet
1. General description
The 74LVCV2G66 is a high-performance, low-power, low-voltage, Si-gate CMOS device
that provides superior performance to most advanced CMOS compatible TTL families.
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.

To avoid drawing V
CC
current out of terminal nZ when switch current flows in terminal nY, the voltage drop
across the bidirectional switch must not exceed 0.4 V. If the switch current flows into terminal nZ, no V
CC
current will flow out of terminal nY. In this case, there is no limit for the voltage drop across the switch.
