74VHCT08A
Quad 2-Input AND Gate
Features
General Description
■ High speed: t = 5.0ns (typ.) at T = 25°C
The VHCT08A is an advanced high speed CMOS 2
Input AND Gate fabricated with silicon gate CMOS tech-
nology. It achieves the high-speed operation similar to
equivalent Bipolar Schottky TTL while maintaining the
CMOS low power dissipation.
PD
A
■ High noise immunity: V = 2.0V, V = 0.8V
IH
IL
■ Power down protection is provided on all inputs and
outputs
■ Low noise: V
= 0.8V (max.)
OLP
The internal circuit is composed of 4 stages including
buffer output, which provide high noise immunity and
stable output.
■ Low power dissipation: I = 2µA (max.) @ T = 25°C
CC
A
■ Pin and function compatible with 74HCT08
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
= 0V. These circuits prevent
CC
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.
