DESCRIPTION
The 74VCXH162244 is a low voltage CMOS 16
BIT BUS BUFFER (NON INVERTED) fabricated
with sub-micron silicon gate and five-layer metal
wiring C
2
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 26Ω 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.
