74VHC27

Triple 3-Input NOR Gate

Features

■ High speed: tPD = 4.1ns (typ) at TA = 25°C

■ Low power dissipation: ICC = 2µA (max) at TA = 25°C

■ High noise immunity: VNIH = VNIL = 28% VCC (min.)

■ Power down protection is provided on all inputs

■ Low noise: VOLP = 0.8V (max.)

■ Pin and function compatible with 74HC27

General Description

The VHC27 is an advanced high speed CMOS 3-Input

NOR Gate fabricated with silicon gate CMOS technol-

ogy. 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. 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 bat-

tery backup. This circuit prevents device destruction due

to mismatched supply and input voltages.
