Description
The 54VCXH162245 is a low voltage CMOS 16
bit bus transceiver (3-state) fabricated with sub-
micron silicon gate and five-layer metal wiring
C2MOS technology. It is ideal for low power and
very high speed 1.65 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
series resistance in the A 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.
