Single-pole single-throw analog switch
Rev. 1 — 27 January 2015
Product data sheet
1. General description
74AHC1G66-Q100 and 74AHCT1G66-Q100 are high-speed Si-gate CMOS devices.
They are single-pole single-throw analog switches. The switch has two input/output pins
(Y and Z) and an active HIGH enable input pin (E). When pin E is LOW, the analog switch
is turned off.
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 drawing V
CC
current from pin Z, when switch-current flows in pin Y, the voltage drop across the bidirectional switch must not
exceed 0.4 V. If switch-current flows into pin Z, no V
CC
current flows out of terminal Y. In this case, there is no limit for the voltage drop
across the switch. However, the voltage at pins Y and Z may not exceed V
CC
or GND.
Applies to control signal levels.
