LTC2862CDD-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2862CDD-1#PBF is a half-duplex RS485/RS422 transceiver in an 8-lead DFN package. It operates on a 3V to 5.5V supply and supports data rates up to 20Mbps or low EMI 250kbps. The device features ±60V fault protection on interface pins, ±15kV ESD protection, and an extended common mode range of ±25V. It includes guaranteed failsafe receiver operation, current-limited drivers, thermal shutdown, and logic-selectable slew rate control.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults to ±60V during all modes including power-down
• Enhanced ESD protection with ±15kV HBM rating on interface pins
• Extended common mode input range of ±25V for reliable operation with large ground loops
• Guaranteed failsafe receiver operation with fully balanced differential thresholds

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA)
• Industrial Control and Instrumentation Networks
• Building Automation, Security Systems and HVAC
• Medical Equipment
• Lighting and Sound System Control

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CDD' corresponds to the commercial temperature grade (0°C to 70°C) and DFN package. Confirm the '-1' designation indicates the half-duplex variant with 20Mbps capability. Ensure the '#PBF' suffix denotes lead-free finish and tube packaging as per the manufacturer's ordering guide.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high voltage fault tolerance is required on RS485/RS422 lines. The half-duplex configuration suits bidirectional communication needs. Consider the 20Mbps speed for standard applications or the 250kbps mode for reduced electromagnetic interference. Verify that the 3V to 5.5V supply range matches the system design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862A family of ruggedized transceivers. It shares pin compatibility with legacy parts like the LT1785 and LT1791. The CDD suffix identifies the commercial grade version in an 8-lead plastic DFN package. Other variants include full-duplex models and industrial/military temperature grades.

Drivers, Receivers, Transceivers Replacement Considerations

LT1785 and LT1791 are pin-compatible alternatives. Verify if the replacement requires the same ±60V fault protection level. Check if the target application necessitates the specific 20Mbps data rate or if lower speeds suffice.
