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 C

MOS 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鈩?series

resistance in the outputs. These resistors permit

to reduce line noise in high speed applications.
