DS36277TN/NOPB

Overview

The DS36277TN/NOPB is a half-duplex RS-485 transceiver manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It supports data transmission rates up to 20 Mb/s with a supply voltage of 5 V. The device operates within a temperature range of -40°C to +85°C and draws 500 µA of quiescent current. It integrates one driver and one receiver for single-ended communication lines.

Feature Summary

• Supports multipoint bus configurations for RS-485 networks
• Provides high-speed data transfer capabilities up to 20 Mb/s
• Operates on a standard 5 V power supply with low standby current

Applications

• Industrial automation control systems
• Building automation and security networks
• Data acquisition and monitoring equipment

Procurement Notes

Verify the specific suffix 'TN' against official Texas Instruments documentation to confirm pinout and package dimensions. Ensure compatibility with existing PCB footprints and thermal requirements before integration into production designs.

Selection Notes

Select this component for applications requiring robust RS-485 communication over moderate distances. Consider the 20 Mb/s speed limit and 5 V operation when designing power and signal integrity constraints for the target system.

Part Context

This part belongs to the DS3627x series of line transceivers designed for noisy industrial environments. It complements other variants like the DS36276 and DS36277MX by offering a specific package configuration suitable for automated assembly processes.

Replacement Considerations

Check for direct equivalents such as the DS36276 or DS36277MX if pin-to-pin compatibility is required. Verify that substitute parts meet the same electrical specifications and operating temperature ranges.
