74HC1G66; 74HCT1G66
Single-pole single-throw analog switch
Rev. 04 — 19 December 2008
Product data sheet
1. General description
74HC1G66 and 74HCT1G66 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.
The non-standard output currents are equal to those of the 74HC4066 and 74HCT4066.

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.
