LTC487CSW#PBF

Drivers, Receivers, Transceivers Overview

The LTC487CSW#PBF is a quad low-power RS-485 line driver manufactured by Analog Devices Inc. It operates on a single 5V supply with a typical quiescent current of 110µA. The device supports data rates up to 10Mb/s and features an extended common mode range from -7V to +12V. It utilizes a 16-lead SOIC package and includes thermal shutdown protection. Electrical specifications are guaranteed over the commercial temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• CMOS design provides significant power savings compared to bipolar counterparts while maintaining ruggedness against overload and ESD damage.
• Thermal shutdown circuit prevents excessive power dissipation by forcing outputs into a high impedance state during overheating.
• Power-up/down glitch-free driver outputs permit live insertion or removal of packages without disrupting the bus.

Drivers, Receivers, Transceivers Applications

• Multipoint data transmission systems adhering to RS-485 standards
• RS-422 compliant communication networks
• Level translation between different voltage domains

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CSW' corresponds to the commercial temperature grade (0°C to 70°C) and the 16-lead plastic SOIC package format. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering details match the exact part number to avoid functional discrepancies related to temperature ratings or packaging types.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low standby power consumption in multipoint bus architectures. The wide common mode range accommodates ground differences between devices. Verify that the required data rate does not exceed 10Mb/s and that the operating environment remains within the specified commercial temperature limits for optimal performance.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC487 series of low-power RS-485 drivers. It is pin-compatible with legacy parts such as the SN75174, DS96174, µA96174, and DS96F174, facilitating direct upgrades in existing designs. The series offers both commercial and industrial temperature variants across DIP and SOIC packages.

Drivers, Receivers, Transceivers Replacement Considerations

Pin-compatible substitutes include SN75174, DS96174, µA96174, and DS96F174. Verify that alternative components meet the specific 110µA typical supply current requirement and the -7V to +12V common mode range specifications before implementation.
