LTC487ISW#PBF

Drivers, Receivers, Transceivers Overview

The LTC487ISW#PBF is a quad low power RS-485 driver manufactured by Analog Devices Inc. It operates on a single 5V supply with a voltage range of 4.75V to 5.25V and features an industrial temperature rating from -40°C to +85°C. The device provides four differential drivers with three-state outputs, supporting data rates up to 10Mb/s. Key electrical specifications include a typical supply current of 110µA, 2kV ESD protection, and thermal shutdown circuitry. It is housed in a 16-lead plastic SOIC (SW) package.

Drivers, Receivers, Transceivers Feature Summary

• Quad low power RS-485/RS-422 differential bus drivers
• Extended common mode range from -7V to +12V
• Thermal shutdown protection against excessive power dissipation
• Glitch-free power-up/down outputs for live insertion

Drivers, Receivers, Transceivers Applications

• Multipoint data transmission systems
• Low power RS-485 and RS-422 interface circuits
• Level translation applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix ISW indicates the Industrial temperature grade (-40°C to +85°C) and SW package type. Confirm RoHS compliance status via official documentation. Ensure the ordering part number matches the required lead finish and tape/reel specifications before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing for multipoint RS-485 networks requiring low quiescent current and extended common mode voltage tolerance. The industrial temperature range suits environments exceeding commercial limits. Verify that the 10Mb/s data rate and 32-unit load capability align with the system's bandwidth and topology requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC487 family of low power RS-485 drivers. It is pin-compatible with legacy parts such as the SN75174 and DS96174. The ISW variant specifically denotes the industrial temperature range and wide SOIC package, distinguishing it from commercial or DIP package alternatives within the same series.

Drivers, Receivers, Transceivers Replacement Considerations

Pin-compatible replacements include SN75174, DS96174, µA96174, and DS96F174. Verify that substitute components meet the specific -40°C to +85°C operating temperature range and 10Mb/s data rate requirements.
