DS36276M/NOPB Description

The DS36276M/NOPB from Texas Instruments is a half-duplex RS-422/RS-485 transceiver designed for robust serial communication in industrial and embedded systems. Housed in an 8-pin SOIC package, this surface-mount IC operates within a 4.75V to 5.25V supply range and supports 1 driver and 1 receiver channel. With a 50 mV receiver hysteresis, it ensures reliable signal integrity in noisy environments. The device is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards. Although marked obsolete, it remains a viable choice for legacy systems requiring stable, low-power differential communication.

DS36276M/NOPB Features

• Half-Duplex Operation: Enables bidirectional communication over a single pair of wires, reducing wiring complexity.
• Wide Supply Range (4.75V–5.25V): Compatible with standard 5V logic systems.
• 50 mV Receiver Hysteresis: Enhances noise immunity, critical for industrial applications.
• RS-422/RS-485 Protocol Support: Ideal for long-distance data transmission (up to 1.2 km) at high speeds.
• Surface-Mount (SOIC-8) Packaging: Saves board space and suits automated assembly.
• Industrial Temperature Range (0°C to 70°C): Reliable performance in moderate environments.
• Low Power Consumption: Optimized for energy-efficient designs.

DS36276M/NOPB Applications

• Industrial Automation: PLCs, motor control, and sensor networks requiring noise-resistant communication.
• Telecom Infrastructure: Base stations and repeaters leveraging RS-485 for robust signaling.
• Embedded Systems: Legacy designs needing 5V-compatible transceivers with minimal footprint.
• Building Automation: HVAC controls and security systems utilizing half-duplex multidrop buses.
• Medical Equipment: Diagnostic devices where signal integrity is paramount.

Conclusion of DS36276M/NOPB

The DS36276M/NOPB offers a balanced combination of noise immunity, 5V compatibility, and compact packaging, making it a pragmatic choice for legacy or cost-sensitive RS-422/RS-485 applications. While obsolete, its proven reliability in industrial and embedded contexts ensures continued relevance in systems prioritizing robustness over cutting-edge features. Designers should evaluate alternatives for new projects but may consider this IC for maintenance or backward-compatible upgrades.
