DS36276M

Overview

The DS36276M is a FailSafe Multipoint Transceiver designed for bi-directional differential buses, compatible with TIA/EIA-485 standards. It guarantees the receiver output to a HIGH state during floating, idle, or line fault conditions (open/short). The device operates within a supply voltage range of 4.75V to 5.25V and supports a bus common mode range from -7V to +12V. It features a wide operating temperature range of 0°C to +70°C and is housed in an 8-pin SOIC package.

Feature Summary

• FailSafe receiver ensures a known HIGH output state under open, terminated, or shorted input conditions
• Compatible with TIA/EIA-485, TIA/EIA-422-A, and CCITT Recommendation V.11 interface standards
• Designed for multipoint transmission on bi-directional differential buses
• Provides separate driver input, enable, receiver enable, and output pins for maximum flexibility

Applications

• Asynchronous controllers such as UARTs requiring guaranteed receiver states
• Multipoint transmission systems on differential buses
• Industrial communication networks utilizing RS-485 or RS-422-A protocols

Procurement Notes

Verify the component manufacturer origin, as Texas Instruments acquired National Semiconductor which originally produced this part. Confirm the specific package marking and date code align with current inventory sources. Ensure the ordering suffix matches the required temperature grade and packaging format for your production needs.

Selection Notes

Select this transceiver when system reliability depends on maintaining a defined logic level during bus faults or idle states. It serves as a pin-compatible replacement for legacy devices like the DS75176B, DS96176, and SN75176A/B. Ensure the application environment remains within the specified 0°C to +70°C operating temperature range.

Part Context

This component belongs to the family of industrial interface transceivers used for robust serial communication. Originally manufactured by National Semiconductor, it is now distributed under the Texas Instruments portfolio. It addresses specific reliability requirements in noisy environments where standard transceivers might fail to provide a deterministic output state.

Replacement Considerations

The datasheet explicitly lists pin-compatible replacements including the DS75176B, DS96176, DS3695, SN75176A, and SN75176B.
