DESCRIPTION
The LVQ245is a low voltage CMOS OCTAL BUS
TRANSCEIVER
(3-STATE)
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology. It is ideal for low
power and low noise 3.3Vapplications.
It has better speed performance at 3.3V than 5V
LSTTL family combined with the true CMOS low
power consumption.
fabricated
with
T
(TSSOPPackage)
This IC is intended for two-way asynchronous
communication between data buses; the direction
of data trasmission is determined by DIR input.
The enable input G can be used to disable the
device so thatthe buses are effectivelyisolated.
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 TERMINAL IS FLOATING
(HIGH IMPEDANCE STATE) IT IS REQUESTED
TO FIX THE INPUT LEVEL BY MEANS OF
EXTERNAL
