DESCRIPTION

The LCX16240A is a low voltage CMOS 16-BIT

BUS BUFFER fabricated with sub-micron silicon

gate and double-layer metal wiring C2MOS

technology. It is ideal for low power and high

speed 3.3V applications; it can be interfaced to

5V signal enviroment for both inputs and outputs.

Any nG control output governs four BUS

BUFFERS. Output Enable input (nG) tied

together gives full 16-bit operation.

When nG is LOW, the outputs are on. When nG

is HIGH, the output are in high impedance state.

This device is designed to be used with 3 state

memory address drivers, etc.

It has better speed performance at 3.3V than 5V

LSTTL family combined with the true CMOS low

power consumption.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
