74VHCT00A
Quad 2-Input NAND Gate

General Description

The VHCT00A is an advanced hi gh-speed CMO S 2-Input
NAND Gate fabricated with silicon gate CMOS technology.
It achieves the high-speed operation similar to equival ent
Bipolar Schottky TTL while maintaining the CMOS low
power dissipation. The internal circuit is composed of 3
stages, including buffer ou tput, which provide high noise
immunity and stable output.

Protection circuits ensu re that 0V to 7V can be applied to
the input pins without reg ard to the supply voltage an d to
the output pins with V

CC

= 0V. These circuits prevent

device destruction due to m ismatched supply and input/
output voltages. This devic e can be use d to inte rfa ce 3V to

5V systems and two supply systems such as battery
backup.

Features

■ High spee d: tPD = 5.0 ns (typ) at TA = 25°C

■ High noise immunity: V

IH

= 2.0V, VIL = 0.8V

■ Power down protection is provided on all inputs and
outputs

■ Low noise: V

OLP

= 0.8V (max)

■ Low power dissipation:

CC

= 2 µA (max) at TA = 25°C

■ Pin and function compatible with 74HCT00

Ordering Code:

Surface mount pack ages are also available on Tape and Reel. Specify by appending the s uffix let te r “X” to the ordering code.

(Note 5)

Note 1: Absolute Maximum Ratings are values beyond which the device
may be damaged or ha ve its useful li fe impaire d. The datab ook specifica­tions should be met, without exception, to ensure that the system design is
reliable over its p ower supp ly, temperature, and ou tput/input loading vari­ables. Fairchild does not recom mend operation outside data book specifica­tions.
