Quad 2-Input NAND Gate
General Description
The VHC/VHCT00 is an advanced high-speed CMOS 2-In-
put NAND Gate fabricated with silicon gate CMOS technolo-
gy. It achieves the high-speed operation similar to equiva-
lent 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 im-
munity and stable output. An input protection circuit insures
that 0V to 7V can be applied to the input pins without regard
to the supply voltage. This device can be used to interface
5V to 3V systems and two supply systems such as battery
backup. This circuit prevents device destruction due to mis-
matched supply and input voltages.

Note 1:
Absolute Maximum Ratings are values beyond
which the device may be damaged or have its useful life
impaired. The databook specifications should be met, with-
out exception, to ensure that the system design is reliable
over its power supply, temperature, and output/input load-
ing variables. National does not recommend operation out-
side databook specifications.
