Single-pole single-throw analog switch
Rev. 04 — 18 December 2008
Product data sheet
1. General description
74AHC1G66 and 74AHCT1G66 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.

To avoid drawing V
CC
current out of pin Z, when switch current flows in pin Y, the voltage drop across the bidirectional switch must not
exceed 0.4 V. If the switch current flows into pin Z, no V
CC
current will flow out of terminal Y. In this case there is no limit for the voltage
drop across the switch, but the voltage at pins Y and Z may not exceed V
CC
or GND.
Applies to control signal levels.
