74LVC2G66
Bilateral switch
Rev. 8 — 2 April 2013
Product data sheet
1. General description
The 74LVC2G66 is a low-power, low-voltage, high-speed Si-gate CMOS device.
The 74LVC2G66 provides two single pole, single-throw analog switch functions. Each
switch has two input/output terminals (nY and nZ) and an active HIGH enable input (nE).
When nE is LOW, the analog switch is turned off.
Schmitt trigger action at the enable inputs makes the circuit tolerant of slower input rise
and fall times across the entire V
CC
range from 1.65 V to 5.5 V.

To avoid sinking GND current from 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 GND current will flow from terminal nY. In this case, there is no
limit for the voltage drop across the switch.
For overvoltage tolerant switch voltage capability, refer to 74LVCV2G66.
Applies to control signal levels.
