DESCRIPTION
The 74LVXC4245 is a dual supply 8 bit
configurable low voltage CMOS OCTAL BUS
TRANSCEIVER fabricated with sub-micron silicon
gate and double-layer metal wiring C

MOS
technology. Designed for use as an interface
between a 5V bus and a 3.3V to 5V 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 5V bus, the B-port
with the 3.3V to 5V bus.
All inputs are equipped with protection circuits
against static discharge, giving them 2KV ESD
immunity and transient excess voltage.
