DESCRIPTION
The 74LVX3245 is a dual supply low voltage
CMOS OCTAL BUS TRANSCEIVER fabricated
with sub-micron silicon gate and double-layer
metal wiring C
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.

Table 1: Order Codes
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.
