The 74LVQ245 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.

This IC of the 74LVQ245 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 of the 74LVQ245 are equipped with 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 PULL DOWN OR PULL UP RESISTOR.
