74LVC1G66-Q100
Bilateral switch
Rev. 1 — 1 August 2012
Product data sheet
1. General description
The 74LVC1G66-Q100 provides one single pole, single-throw analog switch function. It
has two input/output terminals (Y and Z) and an active HIGH enable input pin (E). When E
is LOW, the analog switch is turned off.
Schmitt trigger action at the enable input 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 Z when switch current flows in terminal Y, the voltage drop across the bidirectional switch
must not exceed 0.4 V. If the switch current flows into terminal Z, no GND current flows from terminal Y. In this case, there is no limit for
the voltage drop across the switch.
Applies to control signal levels.
