LTC2863HDD-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2863HDD-1#PBF is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices. It operates on a 3V to 5.5V supply voltage and supports data rates up to 20Mbps. The device features ±60V fault protection on the A, B, Y, and Z pins, ensuring resilience against overvoltage line faults during all modes of operation, including power-down. It provides ±15kV ESD protection on interface pins and an extended common mode range of ±25V. Packaged in an 8-lead DFN (3mm × 3mm) with an exposed pad connected to PCB ground, it operates within a temperature range of –40°C to +125°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade. The 'H' indicates the high-temperature industrial range (-40°C to +125°C), while 'D' denotes the DFN package. Ensure the '#PBF' suffix confirms lead-free finish and RoHS compliance as per manufacturer standards before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex communication with robust fault tolerance. The LTC2863HDD-1#PBF is suitable where high-speed data transmission up to 20Mbps is needed alongside protection against large ground loop voltages. Consider the DFN package for space-constrained designs requiring thermal performance via the exposed pad.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of low-power transceivers. The LTC2863 variant specifically offers full-duplex capability, distinguishing it from the half-duplex LTC2862. The 'HDD-1' designation identifies the high-temperature grade, DFN package, and 20Mbps speed variant within the series.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet notes pin compatibility with LT1785 and LT1791 devices. Verify electrical specifications and package dimensions when substituting these legacy parts or other RS-485 transceivers to ensure functional equivalence in fault protection and signal integrity.
