The 74VCXH1632245 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.

This IC of the 74VCXH1632245 is intended for two-way asynchronous communication between data buses and the irection 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 of the 74VCXH1632245 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.
