DESCRIPTION

The 54VCXH162244 is a low voltage CMOS 16

BIT BUS BUFFER (NON INVERTED) fabricated

with sub-micron silicon gate and five-layer metal

wiring C2MOS technology. It is ideal for low power

and very high speed 2.3 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 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. Bus hold on data

inputs is provided in order to eliminate the need for

external pull-up or pull-down resistor.

The device circuits is including 26

Ω series

resistance in the outputs. These resistors permit

to reduce line noise in high speed applications.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
