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 dissipation.

The internal circuit is composed of 3 stages including
buffer output, which provide high noise immunity and
stable output.

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
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.

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
