LTC2862IS8-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2862IS8-2#TRPBF is a half-duplex RS485/RS422 transceiver manufactured by Analog Devices. It operates on a 3V to 5.5V supply voltage and supports data rates up to 250kbps with low EMI characteristics. The device features ±60V overvoltage fault protection on the interface pins during all modes, including power-down. It provides an extended common mode range of ±25V and includes ±15kV ESD protection on interface pins. Packaged in an 8-lead SOIC (S8) format, it functions within an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the IS grade designation corresponds to the required industrial temperature range of -40°C to +85°C for your application environment. Ensure compatibility with standard 8-lead SOIC footprint requirements during procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault protection against high common mode voltages and ground loops. The 250kbps slew-rate limited mode is suitable for reducing electromagnetic interference in sensitive industrial settings. Verify that the half-duplex configuration aligns with the bidirectional communication needs of the target network topology.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862 family of low-power RS485/RS422 transceivers. It shares pin compatibility with legacy parts like the LT1785 and LT1791, facilitating direct upgrades in existing designs. The IS8-2 variant specifically denotes the industrial temperature grade and the 250kbps data rate option within the SOIC package lineup.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet confirms pin compatibility with LT1785 and LT1791 devices. Designers upgrading from these older components should verify that the new fault protection levels and electrical characteristics meet the system requirements without necessitating major circuit modifications.
