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.

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 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 systems, it achieves high spe ed operation while m aintaining 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
