74LCX38

Low Voltage Quad 2-Input NAND Gate (Open Drain)

with 5V Tolerant Inputs

General Description

The LCX38 contains four 2-input open drain NAND gates.

The inputs tolerate voltages up to 7V allowing the interface

of 5V systems to 3V systems.

The 74LCX38 is fabricated with advanced CMOS technol-

ogy to achieve high speed operation while maintaining

CMOS low power dissipation.
