DS36276M/NOPB

Overview

The DS36276M/NOPB is a FailSafe multipoint transceiver designed for bidirectional differential buses. It operates at a supply voltage of 5V (4.75V to 5.25V) and supports data rates up to 10 Mb/s. The device features one driver and one receiver within an 8-pin SOIC package. It guarantees a HIGH receiver output during floating, idle, or fault conditions. Operating temperatures range from 0°C to +70°C.

Feature Summary

• FailSafe receiver ensures a known HIGH state when the bus is floating, idle, or experiencing open/short faults.
• Compatible with TIA/EIA-485, TIA/EIA-422-A, and CCITT V.11 interface standards.
• Supports wide bus common mode voltage range from -7V to +12V.

Applications

• Asynchronous controllers such as UARTs
• Multipoint transmission systems
• Industrial communication networks

Procurement Notes

Verify that the component matches the exact DS36276M/NOPB designation. Confirm the manufacturer origin aligns with Texas Instruments specifications. Ensure the package type corresponds to the standard SOIC-8 form factor. Validate RoHS compliance status through official documentation before finalizing procurement orders.

Selection Notes

Select this transceiver when bus fault detection is critical for system stability. It serves as a direct pin-compatible replacement for legacy National Semiconductor parts like the SN75176A/B. Verify that the required operating temperature range fits within the commercial 0°C to +70°C limits specified for this model.

Part Context

This component belongs to the DS36276 series of multipoint transceivers. It maintains backward compatibility with earlier industry-standard RS-485 devices while adding enhanced fail-safe logic. The 'M' suffix indicates the specific SOIC-8 package variant used in surface-mount applications.

Replacement Considerations

Pin-compatible replacements include DS75176B, DS96176, DS3695, SN75176A, and SN75176B. Verify electrical characteristics match requirements before substituting these legacy components.

FAQ

What is the receiver output state during a line fault?

The receiver output is guaranteed to be in a HIGH state during open, shorted, or terminated input conditions.

Is the DS36276M/NOPB compatible with RS-422?

Yes, it is compatible with TIA/EIA-422-A (RS-422-A), TIA/EIA-485 (RS-485), and CCITT Recommendation V.11.

Does this device support shutdown modes?

No, the datasheet does not list a dedicated shutdown pin; it utilizes separate driver enable and receiver enable controls.
