DESCRIPTION
The 74VCXHQ163245 is a dual supply low
voltage CMOS 16-BIT BUS TRANSCEIVER
fabricated with sub-micron silicon gate and
five-layer metal wiring C2MOS 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 systems, it
achieves high speed operation while maintaining
the CMOS low power dissipation and limited rise
and fall time (Low EMI).
This IC is intended for two-way asynchronous
communication between data buses and the
direction of data transmission is determined by
nDIR inputs. The enable inputs nG 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 2.5V and 1.8V bus.
All inputs are equipped with protection circuits
against static discharge, giving them 2KV ESD
immunity and transient excess voltage. All floating
bus terminals during High Z State don’t need
external pull-up or pull-down resistor.
