LTC485CS8#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC485CS8#TRPBF is a low-power RS-485 interface transceiver manufactured by Analog Devices Inc. It operates on a single 5V supply with a voltage range of 4.75V to 5.25V and features one driver and one receiver in an 8-lead SOIC package. The device supports data rates up to 2.5Mb/s with typical propagation delays of 30ns and skew of 5ns. Supply current is typically 300μA when enabled and 500μA otherwise. It provides a common mode range from -7V to +12V, thermal shutdown protection, and fail-safe receiver outputs.

Drivers, Receivers, Transceivers Feature Summary

• Low power CMOS design for multipoint data transmission
• Extended common mode range beyond standard supplies
• Thermal shutdown prevents excessive power dissipation
• Fail-safe receiver guarantees high output when inputs are open

Drivers, Receivers, Transceivers Applications

• RS-485 multipoint communication networks
• Level translation between logic and bus lines
• Industrial control systems requiring low power consumption

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging for the commercial grade (C) variant. Confirm the manufacturer is Analog Devices Inc. Ensure the component matches the 8-lead SOIC physical form factor. Cross-reference the datasheet revision history to ensure no obsolete package changes affect availability.

Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring low quiescent current and extended common mode voltage tolerance. It is suitable for designs needing glitch-free driver outputs during power-up or power-down cycles. Consider the 0°C to 70°C operating temperature range for environmental constraints.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC485 series of low-power RS-485/RS-422 transceivers. It is pin-compatible with other variants like the LTC485IS8 but differs in temperature rating. The series is designed to replace older bipolar transceivers while maintaining ruggedness against overload and ESD damage.

Drivers, Receivers, Transceivers Replacement Considerations

LTC485IS8#TRPBF offers the same electrical specifications but operates over an extended industrial temperature range (-40°C to 85°C). Verify if the wider temperature range is required for the specific application environment.
