Product Introduction

Overview

The SN75HVD12D, produced by Texas Instruments, is a 3.3-V differential transceiver designed for balanced transmission lines. It operates in compliance with ANSI standard TIA/EIA-485-A and ISO 8482:1993, making it suitable for multipoint bus-transmission lines. This device combines a 3-state differential line driver and a differential input line receiver, enabling bidirectional data communication. It features a single 3.3-V power supply and is available in an SOIC package.
