74LCX27

Low Voltage Triple 3-Input NOR Gate

with 5V Tolerant Inputs

General Description

The LCX27 contains three 3-input NOR gates. The inputs

tolerate voltages up to 7V allowing the interface of 5V sys-

tems to 3V systems.

The 74LCX27 is fabricated with advanced CMOS technol-

ogy to achieve high speed operation while maintaining

CMOS low power dissipation.
