DESCRIPTION

The 74VCXH16240 is a low voltage CMOS

16-BIT BUS BUFFER (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

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. Bus hold on data

inputs is provided in order to eliminate te 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.
