DESCRIPTION

The 74VCXH16244 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.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
