DESCRIPTION
The LVQ245 is a low voltage CMOS OCTAL BUS
TRANSCEIVER
(3-STATE)
sub-micron silicon gate and double-layer metal
wiring C

MOS technology. It is ideal for low
power and low noise 3.3V applications.
It has better speed performance at 3.3V than 5V
LSTTL family combined with the true CMOS low
power consumption.
fabricated
with
T
(TSSOP Package)
This IC is intended for two-way asynchronous
communicationbeetwen data buses; the direction
of data trasmission is determined by DIR input.
The enable input G can be used to disable the
device so that the buses areeffectively isolated.
All
inputs and
outputs
protectioncircuits 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
