DESCRIPTION

O
The 74ALVCR162245 is a low voltage CMOS 16
BIT BUS TRANSCEIVER 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 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 busses; the
direction of data transmission is determined by
DIR input. The enable input G can be used to
disable the device so that the busses are
effectively isolated.
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.
