DESCRIPTION
The 74VCXHR162245 is a low voltage CMOS 16
BIT BUS TRANSCEIVER (3-STATE) 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.
This IC is intended for two-way asynchronous
communication between data buses; the direction
of data transmission is determined by DIR input.
The two enable inputs nG can be used to disable
the device so that the buses are effectively
isolated. The device circuits is including 26鈩?/div>
series resistance in the A and B port outputs.
These resistors permit to reduce line noise in high
speed applications. 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. All floating bus terminals during High Z
State must be held HIGH or LOW.
