Bilateral switch
Rev. 3 — 30 October 2018
Product data sheet
1. General description
The 74LVC2G66-Q100 is a low-power, low-voltage, high-speed Si-gate CMOS device.
The 74LVC2G66-Q100 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.

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.
Applies to control signal levels.
