LTC2862IDD-2#PBF

Drivers, Receivers, Transceivers Overview

The LTC2862IDD-2#PBF is a half-duplex RS485/RS422 transceiver in an 8-lead DFN package. It operates on a 3V to 5.5V supply with a maximum data rate of 250kbps. The device features ±60V fault protection on transmission lines and supports an extended common mode range of ±25V. It includes ±15kV ESD protection on interface pins, guaranteed failsafe receiver operation, and thermal shutdown.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults up to ±60V during all modes
• Low EMI slew-rate limited data transmission at 250kbps
• Extended common mode input range of ±25V for noisy environments
• Fully balanced differential receiver thresholds ensure low duty cycle distortion

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA)
• Industrial control and instrumentation networks
• Automotive and transportation electronics
• Building automation, security systems, and HVAC

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix IDD-2 against official Analog Devices documentation to confirm the industrial temperature grade (-40°C to +85°C) and the 250kbps slew-limited data rate. Ensure the DFN-8 package matches the design footprint requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high noise immunity and robust fault tolerance are required for long-distance serial communication. The 250kbps mode is suitable for applications prioritizing electromagnetic compatibility over raw speed. Verify that the system ground loop voltages remain within the specified ±25V common mode limit.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862A series of ruggedized transceivers designed for harsh industrial environments. It shares pinout compatibility with legacy parts like the LT1785 and LT1791, facilitating direct upgrades where higher fault protection is needed without redesigning the PCB layout.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2862IDD-1#PBF offers identical packaging and protection but supports a 20Mbps data rate instead of 250kbps.
