Product Overview
The SN74LVCH16652ADGGR is a 16-bit bus transceiver from Texas Instruments, designed for asynchronous communication between two data buses. It features dual supply voltage operation (3.3V core with 5V tolerant I/O) and is housed in a compact 56-TSSOP package. This device supports bidirectional data flow with direction control (DIR) and output enable (OE) pins, making it ideal for multiplexed data buses in mixed-voltage systems.
