t_PLHt_PHL

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 that the buses are effectively isolated.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

DESCRIPTION

The LVQ245 is a low voltage CMOS OCTAL BUS

TRANSCEIVER (3-STATE) fabricated with

sub-micron silicon gate and double-layer metal

wiring C²MOS 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.

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 PULL DOWN OR PULL UP

RESISTOR.
