DESCRIPTION
The LCX16245 is a low voltage CMOS 16-BIT
BUS TRANSCEIVER (3-STATE) fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology. It is ideal for low
power and high speed 3.3V applications; it can
be interfaced to 5V signal enviroment for both
inputs and outputs.
This IC is intended for two-way asynchronous
communicationbeetwen data buses; the direction
of data trasmission is determined by DIR input.
The two enable inputs nG can be used to disable
the device so that the buses are effectively
isolated. It has better speed performance at 3.3V
than 5V LSTTL family combined with the true
CMOSlow power consumption.
All
inputs
and
outputs are
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
IT IS PROHIBITED TO APPLY A SIGNAL TO A
TERMINAL WHEN IT IS IN OUTPUT MODE
AND WHEN A BUS THERMINAL IS FLOATING
(HIGH IMPEDANCE STATE) IT IS REQUESTED
TO FIX THE INPUT LEVEL BY BEANS OF
