DESCRIPTION

The 74LVX3245 is a dual supply low voltage

CMOS OCTAL BUS TRANSCEIVER fabricated

with sub-micron silicon gate and double-layer

metal wiring C2MOS technology. Designed for use

as an interface between a 5V bus and a 3.3V bus

in a mixed 5V/3.3V supply systems, it achieves

high speed operation while maintaining the CMOS

low power dissipation.

This IC is intended for two-way asynchronous

communication between data buses and the

direction of data transmission is determined by

DIR input. The enable input G can be used to

disable the device so that the buses are effectively

isolated.

The A-port interfaces with the 3V bus, the B-port

with the 5V bus.

All inputs are equipped with protection circuits

against static discharge, giving them 2KV ESD

immunity and transient excess voltage.
