DESCRIPTION

The 74ALVCH16244 is a low voltage CMOS 16

BIT BUS BUFFER (NON INVERTED) fabricated

with sub-micron silicon gate and five-layer metal

wiring C MOS technology. It is ideal for low power

and very high speed 1.65 to 3.6V applications; it

can be interfaced to 3.6V signal environment for

both inputs and outputs.

Any nG output control governs four BUS

BUFFERS. Output Enable input (nG) tied together

gives full 16-bit operation.

When nG is LOW, the outputs are enabled. When

nG is HIGH, the output are in high impedance

state.

Active bus-hold circuitry is provided to hold

unused or floating data inputs at a valid logic level.

This device is designed to be used with 3 state

memory address drivers, etc.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
