DESCRIPTION
The 74LVXC3245 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
2
MOS
technology. Designed for use as an interface
between a 3.3V bus and a 3.3V to 5V bus in a
mixed 3.3V/5V supply systems, it achieves high
speed operation while maintaining the CMOS low
power dissipation.
PIN CONNECTION AND IEC LOGIC SYMBOLS
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.
