Texas Instruments SN75176BDR RS422 / RS485 Transceiver SOIC-8
Texas Instruments SN75176BDR RS422/RS485 differential bus transceiver in SOIC-8 package, supporting up to 32 nodes on multipoint bus lines.
The Texas Instruments SN75176BDR RS422 / RS485 Transceiver is a differential bus transceiver in an SOIC-8 package, designed for reliable bidirectional data communication on multipoint bus transmission lines.
Overview
This integrated circuit combines a 3-state differential line driver and a differential input line receiver, both powered from a single 5 V supply (4.75 V to 5.25 V). It is designed for long bus lines where electrical noise is a concern and supports up to 32 nodes. Its design adheres to ANSI TIA/EIA-422-B, TIA/EIA-485-A, and ITU recommendations V.11 and X.27, supporting compatibility in balanced line applications.
Key Features
- Active-high and active-low enable pins for the driver and receiver, which can be tied together externally for direction control
- Differential I/O bus ports that present minimal loading to the bus when the driver is disabled or unpowered
- Wide positive and negative common-mode voltage ranges, suitable for party-line applications
- Thermal shutdown protection and positive and negative driver output current limiting
- Manufactured without antimony or brominated flame retardants (no Sb/Br)
Applications
Typical application areas include industrial automation and control systems, communications networking equipment, point-of-sale systems, and industrial instrumentation. It is also suited to any application requiring robust, long-distance, multi-drop serial data communication.
