LTC2864IS-2#PBF

Drivers, Receivers, Transceivers Overview

The LTC2864IS-2#PBF is a low-power, full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply voltage and supports a maximum data rate of 250kbps with slew-rate limiting for reduced EMI. The device features ±60V fault protection on transmission lines during all modes, including power-down. It provides ±15kV HBM ESD protection on interface pins and an extended common mode range of ±25V. Packaged in a 14-lead SOIC, it functions within an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure the component matches the required RS-485/RS-422 protocol specifications before integration. Cross-reference the datasheet revision date to validate electrical characteristics and pin configurations.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring robust fault tolerance against large ground loop voltages. The 250kbps slew-limited mode is suitable for reducing electromagnetic interference in electrically noisy environments. Verify that the system logic levels are compatible with the 3V to 5.5V supply requirements.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC286x family of fault-protected transceivers. It shares pin compatibility with legacy parts like the LT1785 and LT1791. The 'I' suffix indicates the industrial temperature range, while the '-2' designation specifies the 250kbps data rate variant.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet confirms pin compatibility with the LT1785 and LT1791. Verify functional equivalence regarding fault protection ratings and common mode ranges when substituting these legacy components.
