DESCRIPTION

The 74VCX1632245 is a dual supply low voltage
CMOS 16-BIT BUS TRANSCEIVER fabricated
with sub-micron sil icon gate and five-layer metal
wiring C

2

MOS technology . Designed for use as an
interface between a 3.3V bus and a 2.5V or 1.8V
bus in a mixed 3.3V/1.8V,3.3V/2.5V and 2.5V/

1.8V supply syste ms, it achieves high speed
operation while maintaining the CMOS low power
dissipation.
This IC is intended f or two-way asynchronous
communication between data buses and the
direction of data transmission is determined by
nDIR inputs. The enable inputs nG

canbeusedto
disable the device so that the bus es are effectively
isolated. The A-port interfaces with the 3V bus, the
B-port with the 2.5V and 1.8 V bus.
All inputs are equipped with protection circuits
against static discharge, giving them 2KV ESD im­munity and transient excess voltage. A ll floating
bus t erminals during High Z State must be held
HIGH or LOW.
