This is a document about a low voltage CMOS 16-bit bus buffer transceiver (3-state). The product features include 1.65 to 3.6V inputs and outputs, high speed performance, 3.6V tolerance on inputs and outputs, power down protection, etc.
The 54VCXHR162245 is a low voltage CMOS 16-bit bus transceiver fabricated with C²MOS technology. It supports operating voltages from 1.65 V to 3.6 V and features symmetrical impedance outputs with built-in series resistors to reduce line noise. The device includes power-down protection, bus hold functionality, and is designed for two-way asynchronous communication between data buses.
