LTC486ISW#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC486ISW#TRPBF 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 range 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 parameters include a typical supply current of 110µA, propagation delays of 28ns typical (50ns max), and output skew of 5ns typical. It includes thermal shutdown protection and glitch-free outputs for live insertion.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the ISW variant corresponds to the SW package and industrial temperature grade (-40°C to +85°C). Ensure compatibility with existing PCB footprints for the 16-lead plastic SOIC wide package before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC486ISW#TRPBF for designs requiring quad differential drivers with low quiescent current. This part is suitable for systems needing extended common-mode range and thermal protection. Verify that the required data rate does not exceed 10Mb/s and that the operating environment falls within the specified industrial temperature limits.

Drivers, Receivers, Transceivers Part Context

The LTC486 belongs to the family of low power RS-485 interface ICs from Analog Devices. It serves as a line driver counterpart to receivers like the LTC488. The ISW designation specifies the industrial temperature range and surface-mount packaging, distinguishing it from commercial variants or through-hole DIP packages within the same functional family.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet lists pin-compatible replacements including the SN75172, DS96172, µA96172, and DS96F172. For higher speed requirements, consider the LTC1688/LTC1689 series.
