DS36277TM/NOPB

Overview

The DS36277TM/NOPB is a half-duplex RS-422/RS-485 transceiver manufactured by Texas Instruments. It integrates one driver and one receiver in an SOIC-8 package, supporting data rates up to 20 Mb/s. The device operates on a single 5 V supply with a typical quiescent current of 500 uA. It functions within an industrial temperature range from -40°C to +85°C. This component is designed for multipoint communication systems requiring reliable differential signaling.

Feature Summary

• Supports multipoint bus configurations for RS-422 and RS-485 networks
• Provides high-speed data transmission capability up to 20 Mb/s
• Operates efficiently with low power consumption characteristics

Applications

• Industrial automation control systems
• Building automation and security networks
• Multipoint data acquisition setups

Procurement Notes

Verify the specific suffix 'TM' indicates tape and reel packaging when sourcing. Confirm the 'NOPB' designation ensures lead-free and RoHS compliance status. Cross-reference the manufacturer part number against official datasheets to ensure compatibility with existing circuit designs before finalizing orders.

Selection Notes

Select this component for applications requiring a single transceiver on a shared bus line. Ensure the system voltage matches the specified 5 V requirement. Consider the SOIC-8 footprint constraints during PCB layout planning. Verify that the required data rate does not exceed the 20 Mb/s limit for optimal signal integrity.

Part Context

This device belongs to the DS36277 series of interface ICs from Texas Instruments. It serves as a fundamental building block for serial communication links in noisy environments. The component complements other drivers and receivers in the broader RS-485 ecosystem.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family. Verify electrical specifications match exactly if substituting with similar RS-485 transceivers.
