Product Overview
The SN74LVTH16652DL from Texas Instruments is a 16-bit bus transceiver designed for 3.3-V VCC operation, with 5-V tolerant I/Os and bus-hold circuitry. It provides bidirectional data flow between two buses (A and B) with direction control via the DIR input and output enable via the OE input. The device is ideal for driving high-capacitance loads and is available in a 56-pin SSOP package.
