DESCRIPTION
74HC1G66; 74HCT1G66
The 74HC1G/HCT1G66 is a high-speed Si-gate CMOS
device.
The 74HC1G/HCT1G66 provides an analog switch. 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 compared to
the 74HC/HCT4066.

LIMITING VALUES

Notes
1. 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.
2. Above 55
°C
the value of P
D
derates linearly with 2.5 mW/K.
