SN75HVD12P TI RS-485 Transceiver | 8-PDIP | 3.3V, 250kbps

Product Overview

The SN75HVD12P from Texas Instruments is a differential line transceiver designed for RS-485 and RS-422 communication. It operates from a single 3.3V supply and features a driver output capable of handling up to 32 nodes on a bus. The device is housed in an 8-pin PDIP package, making it suitable for through-hole PCB assembly. With a signaling rate of up to 250 kbps, it is ideal for industrial automation, building automation, and telecom infrastructure.
