The SN75176BDR is an 8pin SOP RS485/RS422 transceiver based on the SN75176B device. It provides a differential twowire bus driver and receiver in a single package, designed for reliable halfduplex serial communications. This listing is for 10 pieces per lot in the SOP8 surfacemount (SMD) package. Key benefits Enables reliable differential twowire RS485/RS422 communication, improving noise immunity and allowing longer link distances on industrial and commercial networks. Supports multipoint bus topologies common in automation, control, and instrumentation projects. Simple microcontroller interface through DI (data input), RO (receiver output), and control pins DE (driver enable) and RE (receiver enable), enabling straightforward direction and data control. Compact SOP8 package suitable for spaceconstrained PCB layouts and surfacemount assembly. Designed for robust operation in challenging environments, with receiver behavior defined under idle, open, or fault conditions to maintain stable bus signaling. Key attributes Model: SN75176B in SN75176BDR variant Package: 8pin SOP (SOP8), surfacemount device (SMD) Function: RS485/RS422 transceiver with integrated driver and receiver Bus interface: A and B differential lines Control: DI, RO, DE, RE pins for data input, data output, driver enable, and receiver enable Power: singlesupply operation (typical 5V class, aligned with standard RS485 interfaces) Intended use: compatible with RS485 and RS422 networks, suitable for multipoint and pointtopoint configurations Applications and use cases Industrial automation networks: connect PLCs, remote I/O modules, and field devices over RS485 for reliable multipoint data exchange. Building automation and HVAC systems: enable robust communication between controllers and sensors/actuators across longer cable runs. Embedded/microcontroller projects: implement a robust RS485 interface for distributed sensor networks or remote data collection on a shared bus. This listing provides 10 pieces of SN75176BDR in SOP8 (SMD) format, preserving the standard SN75176B features and compatibility for RS485/RS422 applications.
