STMicroelectronics Intros 74VCX1632245 Transceiver

STMicroelectronics Inc. (ST, Geneva, Switzerland) announced the new 74VCX1632245 16-bit, dual supply bus transceiver level translator, which is available in a TFBGA54 package, 48-pin TSSOP, or 42-pin FPGA package, and is targeted for use in applications such as mobile phones, PDAs and motherboards.

The device provides a two-way, asynchronous, communications interface between buses at 3.3V and 2.5V or 1.8V in mixed 3.3V/1.8V, 3.3V/2.5V, or 2.5V/1.8V supply systems. It expands the company's existing VCX product line and is built on a sub-micron, silicon gate and triple-layer, metal, CMOS process, giving it high speed and low power dissipation.

It also offers symmetrical output impedance and balanced propagation delays. All the inputs have protection circuits against static discharge, giving them 2kV ESD immunity and transient excess voltage. The parts also have power-down protection on the inputs and outputs.
