DESCRIPTION
The 74LCXH16245 is a low voltage CMOS 16 BIT
BUS TRANSCEIVER (3-STATE) fabricated with
sub-micron silicon gate and double-layer metal
wiring C
and high speed 3.3V applications; it can be
interfaced to 5V 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 isolat-
ed.
Bus hold on data inputs is provided in order to
eliminate the need for external pull-up or
pull-down resistor.
It has same speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power con-
sumption.
All inputs and outputs are equipped with protec-
tion 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.
