The SN75176BDR from Texas Instruments is a robust and reliable half-duplex transceiver designed for RS-422 and RS-485 communication systems. It supports bidirectional data transmission and meets or exceeds the requirements of ANSI Standards TIA/EIA-422-B, TIA/EIA-485-A, and ITU recommendations V.11 and X.27, ensuring compatibility with industrial and commercial communication standards. Engineered for use in noisy environments and long bus lines, the SN75176BDR provides stable performance with its differential signaling capability, allowing multiple devices to share the same communication line without interference. The device operates from a single 5-V power supply, simplifying system design while maintaining dependable data integrity in demanding applications.
This transceiver integrates a 3-state driver and receiver, both featuring independent enable functions for flexible control in multipoint networks. It offers wide positive and negative bus voltage ranges and supports up to ±60 mA of driver output current, along with built-in current limiting and thermal shutdown protection for enhanced reliability. The receiver section provides a high input impedance of 12 kΩ (minimum), ±200 mV input sensitivity, and typical input hysteresis of 50 mV to ensure stable and accurate signal detection. Housed in an 8-SOIC package, the SN75176BDR is ideal for use in industrial automation, instrumentation, and communication interfaces where noise immunity and signal robustness are essential.
