LTC1535ISW#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1535ISW#TRPBF is an isolated RS-485 transceiver manufactured by Analog Devices Inc. It integrates a single driver and receiver within a 28-pin SOIC package, supporting half-duplex and full-duplex communication modes at data rates up to 250 kb/s. The device operates on a supply voltage ranging from 4.5 V to 7.5 V with a typical operating current of 63 mA. It features robust electrostatic discharge protection rated at 8 kV and functions reliably across a commercial temperature range of 0°C to +70°C. This component provides galvanic isolation for reliable serial data transmission in industrial environments.

Drivers, Receivers, Transceivers Feature Summary

• Provides galvanic isolation for RS-485 interface applications
• Supports both half-duplex and full-duplex communication protocols
• Integrates high-voltage ESD protection capabilities

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building management and security networks
• Process control instrumentation

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the ISW designation corresponds to the required commercial temperature grade for your operational environment. Ensure compatibility with existing board layouts designed for the 28-SOIC footprint before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this model when designing systems requiring isolated RS-485 connectivity without external isolation barriers. Compare against the CSW variant if extended industrial temperature ranges are necessary. Evaluate power consumption requirements against the specified 63 mA operating current to ensure adequate thermal management within the enclosure design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1535 series of isolated transceivers. It shares functional similarities with the LTC1535ISW#PBF but differs in packaging format. The series addresses the need for reliable serial communication in electrically noisy environments where signal integrity is critical.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC1535ISW#PBF serves as a direct pin-compatible alternative offering tube packaging instead of reel packaging. Verify that any substitute maintains identical isolation ratings and electrical specifications to ensure system compliance.
