74VHC27
Triple 3-Input NOR Gate
General Description
The VHC27 is an advanced high speed CMOS 3-Input
NOR 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 out-
put. An input protection circuit insures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery backup. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
Features
s High speed: tPD = 4.1 ns (typ) at TA = 25°C
s Low power dissipation: ICC = 2 µA (max) at TA = 25°C
s High noise immunity: VNIH = VNIL = 28% VCC (min)
s Power down protection is provided on all inputs
s Low noise: VOLP = 0.8V (max)
s Pin and function compatible with 74HC27

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: Unused inputs must be held HIGH or LOW. They may not float.
