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 (Yand 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.
2. Features
n Wide supply voltage range from 2.0 V to 10.0 V for the 74HC1G66
n Very low ON resistance:
u 45 (typ.) at V
CC
= 4.5 V
u 30 (typ.) at V
CC
= 6.0 V
u 25 (typ.) at V
CC
