CY74FCT163245APVC TI Bus Transceiver | 16-bit | 3.3V, 5V Tolerant

Product Overview

The CY74FCT163245APVC from Texas Instruments is a 16-bit (dual 8-bit) non-inverting bus transceiver designed for asynchronous communication between data buses. It operates with a 3.3V supply voltage while being 5V tolerant on I/O pins, making it ideal for mixed-voltage systems. The device features two separate enable controls (nOEAB and nOEBA) for each 8-bit section, allowing bidirectional data flow with direction control via nDIR pins. Housed in a 48-pin SSOP package, it offers high drive capability (64 mA sink/32 mA source) and low propagation delays (typical 4.1 ns).
