DESCRIPTION
The 74ALVCH16245 is a low voltage CMOS 16
BIT
BUS
TRANSCEIVER
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
busses;
the
direction of data transmission is determined by
DIR input. The enable input G canbe usedto
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.
