DS36277TMX/NOPB

Overview

The DS36277TMX/NOPB is a half-duplex RS-422/RS-485 transceiver manufactured by Texas Instruments. It integrates one driver and one receiver within an SOIC-8 surface-mount package. The device supports data transmission rates up to 20 Mb/s and operates on a fixed 5 V supply voltage. It draws a typical operating supply current of 500 uA. The component functions reliably across an industrial temperature range from -40°C to +85°C. Designed for multipoint bus applications, it lacks a shutdown pin, ensuring continuous operation without standby modes.

Feature Summary

• Supports high-speed data communication with a maximum rate of 20 Mb/s
• Enables bidirectional data transfer on multipoint buses via differential signaling
• Operates exclusively at a 5 V logic supply voltage
• Provides robust performance in industrial environments across extended temperature ranges

Applications

• Multipoint serial communication networks requiring RS-485 compliance
• Industrial automation systems utilizing RS-422 or RS-485 protocols
• Building automation and control systems needing reliable half-duplex data links

Procurement Notes

Verify the specific suffix NOPB indicates lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm the SOIC-8 package dimensions and pinout match the design requirements before integration. Ensure the 5 V supply rail stability meets the device's operational specifications for optimal signal integrity.

Selection Notes

Select this component when a single half-duplex transceiver is required for RS-422 or RS-485 networks. It is suitable for designs needing 20 Mb/s throughput without the complexity of full-duplex architectures. Consider the fixed 5 V requirement and lack of shutdown functionality during system power management planning.

Part Context

This part belongs to the DS36277 series of interface ICs from Texas Instruments. It serves as a line transceiver specifically engineered for noisy industrial environments. The device complements other interface solutions by providing a cost-effective, low-power option for standard multipoint bus topologies.

Replacement Considerations

The DS36276MX/NOPB is a related transceiver in the same family but may differ in specific electrical characteristics or feature sets such as shutdown capabilities. Verify functional equivalence regarding data rate and voltage levels before substitution.
