LTC1535CSW#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1535CSW#TRPBF is an isolated RS-485 transceiver manufactured by Analog Devices Inc., housed in a 28-pin SOIC package. It supports data rates up to 250 kb/s and operates on a supply voltage ranging from 4.5 V to 7.5 V, with a maximum operating current of 63 mA. The device provides 2500 VRMS electrical isolation via an internal capacitive barrier and utilizes a 420 kHz push-pull converter for self-powering the isolated side. It features 8 kV ESD protection on both driver outputs and receiver inputs, along with fault-tolerant capabilities including short-circuit current limiting and thermal shutdown.

Drivers, Receivers, Transceivers Feature Summary

• Provides 2500 VRMS galvanic isolation through an integrated capacitive barrier to break ground loops.
• Features a self-powered architecture using an internal 420 kHz push-pull converter on the isolated side.
• Includes comprehensive protection mechanisms such as 8 kV ESD tolerance, short-circuit current limiting, and thermal shutdown.

Drivers, Receivers, Transceivers Applications

• Industrial systems requiring isolation to handle large common-mode voltages.
• RS-485 networks where grounding loops must be eliminated.
• Isolated analog-to-digital converter interfaces, such as those paired with LTC2402.

Drivers, Receivers, Transceivers Procurement Notes

Verify the #TRPBF suffix indicates tape-and-reel packaging when sourcing components. Confirm that the specific lot meets RoHS compliance standards required for your assembly process. Ensure the supplier provides valid traceability documentation for this Analog Devices part number to maintain quality control integrity during procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing RS-485 or RS-422 interfaces requiring high-voltage isolation without external power supplies on the isolated side. The 250 kb/s speed suits standard industrial communication needs. Consider the 28-pin SW package constraints and verify that the 4.5 V to 7.5 V supply range aligns with the system's power distribution network requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1535 series of isolated RS-485 transceivers. It shares core functionality with variants like the LTC1535ISW#PBF but differs in packaging format. The series is designed for robust communication in electrically noisy environments, offering a compact solution for integrating isolated serial communication into embedded systems.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other LTC1535 variants such as LTC1535ISW#PBF or LTC1535CSW#PBF, which share identical electrical specifications. Verify pin compatibility and ensure the alternative packaging type meets the board layout requirements before substitution.
