SN65LBC180DG4

Drivers, Receivers, Transceivers Overview

The SN65LBC180DG4 is a low-power RS-485 transceiver manufactured by Texas Instruments, designed for half-duplex communication on balanced lines. It integrates one driver and one receiver within a 14-pin SOIC package. The device operates with a supply voltage range of 4.75 V to 5.25 V and supports data rates up to 10 Mb/s. Key electrical specifications include a propagation delay of 22 ns and an operating supply current of 4 mA. It provides robust protection against electrostatic discharge (ESD) with ratings up to 4 kV. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Low-power operation suitable for battery-powered or energy-efficient systems
• Integrated ESD protection for enhanced signal integrity in noisy environments
• Shutdown mode capability to minimize power consumption during idle periods

Drivers, Receivers, Transceivers Applications

• Industrial automation control networks
• Building automation and security systems
• Data acquisition systems requiring long-distance communication

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DG4' indicates lead-free packaging compliant with RoHS standards. Confirm the SOIC-14 package dimensions match the PCB footprint requirements. Ensure the ordering information aligns with the manufacturer's current datasheet revision to avoid discrepancies in pinout or electrical characteristics.

Drivers, Receivers, Transceivers Selection Notes

Select this component when half-duplex RS-485 communication is required at speeds up to 10 Mb/s. It is appropriate for designs needing low quiescent current and integrated ESD protection. Consider the SOIC-14 package constraints for surface-mount assembly. Verify that the 5 V supply voltage range matches the system power rails.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN65LBC180 family of low-power RS-485 transceivers. It shares functional similarities with other members like the SN65LBC180N but differs in package type. The DG4 suffix specifically denotes a lead-free variant of the standard SN65LBC180D, adhering to environmental compliance standards while maintaining identical electrical performance.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include the SN65LBC180DR for reel-packaged equivalents. Cross-reference with SN65LBC180ADRG4 for updated RoHS3 compliance versions. Ensure any substitute maintains the 14-pin SOIC footprint and 10 Mb/s data rate capability.
