SN75HVD1176DR Description

The SN75HVD1176DR from Texas Instruments is a high-speed RS-422/RS-485 transceiver designed for robust differential communication in industrial and commercial applications. Housed in an 8-pin SOIC package, this half-duplex transceiver integrates one driver and one receiver, supporting data rates up to 40 Mbps. Operating within a 4.75V to 5.25V supply range, it ensures reliable performance in environments with 0°C to 70°C ambient temperatures. The device features 40 mV of receiver hysteresis, enhancing noise immunity in electrically noisy conditions. Although marked as obsolete, it remains a viable solution for legacy systems requiring RoHS3-compliant, REACH-unaffected components.

SN75HVD1176DR Features

• High-Speed Operation: Supports 40 Mbps data rates, ideal for time-critical applications.
• Robust Noise Immunity: 40 mV receiver hysteresis minimizes signal errors in noisy environments.
• Wide Supply Range: 4.75V–5.25V operation ensures compatibility with standard 5V systems.
• Compact & Reliable: 8-SOIC surface-mount package with MSL 1 (unlimited) moisture sensitivity, suitable for automated assembly.
• Compliance: RoHS3-compliant, REACH-unaffected, and meets ECCN 5A991B1 export controls.
• Protocol Support: Optimized for RS-422/RS-485 standards, enabling long-distance communication.

SN75HVD1176DR Applications

• Industrial Automation: Used in PLC networks, motor control, and sensor interfaces requiring noise-resistant communication.
• Telecom Infrastructure: Ideal for base stations and backhaul equipment demanding high-speed differential signaling.
• Legacy System Upgrades: Suitable for retrofitting older RS-485/RS-422 systems without redesigning power supplies.
• Building Automation: Deployed in HVAC controls and lighting systems where half-duplex communication suffices.

Conclusion of SN75HVD1176DR

The SN75HVD1176DR offers a balance of speed, noise immunity, and compliance, making it a pragmatic choice for industrial and telecom applications. While obsolete, its 40 Mbps capability and robust hysteresis provide advantages over slower transceivers. Engineers seeking a drop-in solution for legacy or cost-sensitive designs will find this transceiver a reliable option, despite newer alternatives being available.
