LTC2862HS8-2#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862HS8-2#PBF is a half-duplex RS-485/RS-422 transceiver housed in an 8-lead SOIC package. It operates on a 3V to 5.5V supply and supports data rates up to 20Mbps or low EMI 250kbps modes. The device features ±60V overvoltage fault protection on interface pins during all operational states, including power-down. It provides an extended common mode range of ±25V and enhanced ESD protection rated at ±15kV HBM on interface pins. The component includes current-limited drivers, thermal shutdown, and guaranteed failsafe receiver operation.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'H' indicates the industrial temperature grade (-40°C to +125°C) and 'S8' denotes the SOIC-8 package. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering code matches the required duplex and data rate specifications before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring robust fault tolerance against large ground loop voltages. The HS variant is suitable for industrial environments demanding extended temperature ranges. Verify that the half-duplex configuration aligns with the system's communication protocol requirements.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of low-power transceivers. The LTC2862 specifically designates the half-duplex variant within this series, sharing core protection features with full-duplex counterparts while differing in pinout and driver/receiver configuration.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet notes pin compatibility with LT1785 and LT1791 devices. Verify electrical parameters and package dimensions before substituting these legacy components.
