74VHCT00A
Quad 2-Input NAND Gate
General Description
The VHCT00A is an advanced high-speed CMOS 2-Input
NAND Gate 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 VCC = 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.
Features
s High speed: tPD = 5.0 ns (typ) at TA = 25°C
s High noise immunity: VIH = 2.0V, VIL = 0.8V
s Power down protection is provided on all inputs and
outputs
s Low noise: VOLP = 0.8V (max)
s Low power dissipation:
ICC = 2 µA (max) at TA = 25°C
s Pin and function compatible with 74HCT00

Note 1: Absolute Maximum Ratings are values beyond which the device
may be damaged or have its useful life impaired. The databook specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside databook specifica-
tions.
Note 2: HIGH or LOW state. IOUT absolute maximum rating must be
observed.
Note 3: VCC = 0V.
Note 4: VOUT < GND, VOUT > VCC (Outputs Active)
Note 5: Unused inputs must be held HIGH or LOW. They may not float.
