SN74ACT1284NSR TI Bus Transceiver | 20-SO | 5V, 8-bit

Product Overview

The SN74ACT1284NSR from Texas Instruments is a high-performance 8-bit bus transceiver designed for bidirectional asynchronous communication between data buses. It features dual supply voltage operation (VCCA and VCCB) for voltage-level translation, making it ideal for mixed-voltage systems. The device is housed in a 20-pin SOIC package (20-SO) and operates over a wide temperature range of -40°C to +85°C.
