74VHCT04A
Hex Inverter
General Description
The VHCT04A is an advanced high speed CMOS Inverter
fabricated with silicon gate CMOS technology. It achieves
the high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissi-
pation.
The internal circuit is composed of 3 stages including buffer
output, which provide high noise immunity and stable out-
put.
Protection circuits ensure that 0V to 7V can be applied to
the input pins without regard to the supply voltage and to
the output pins with V
CC
=
0V. These circuits prevent
device destruction due to mismatched supply and input/
output voltages. This device can be used to interface 3V to
5V systems and two supply systems such as battery
backup.
