LTC2862HS8-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2862HS8-1#TRPBF is a half-duplex RS485/RS422 transceiver 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. The device features ±60V overvoltage fault protection on interface pins during all modes, including power-down. It provides ±15kV ESD protection on interface pins and ±8kV on other pins. The extended common mode range is ±25V with guaranteed failsafe receiver operation. The operating temperature range is -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on data transmission lines across all operational states.
• Features enhanced ESD protection rated at ±15kV HBM on interface pins without latchup.
• Supports high-speed 20Mbps communication or low EMI 250kbps slew-rate limited mode.
• Ensures reliable data integrity with fully balanced differential receiver thresholds for low duty cycle distortion.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing this component. Confirm the HS grade designation corresponds to the required -40°C to +125°C industrial temperature range for your application environment. Ensure compatibility with standard 8-lead SOIC footprint requirements during procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select this part for half-duplex RS485/RS422 applications requiring robust fault tolerance against line faults up to ±60V. Choose the HS variant specifically when operation within the -40°C to +125°C temperature range is mandatory. Consider the 20Mbps rate for general use or the 250kbps mode if electromagnetic interference reduction is critical.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of low-power transceivers. The LTC2862 specifically denotes the half-duplex configuration within this series. Other variants in the family offer full-duplex capabilities or additional logic supply pins, but this model focuses on single-directional data flow with integrated fault protection.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet notes pin compatibility with LT1785 and LT1791 devices. Verify electrical specifications and package dimensions before substituting these legacy parts. No other direct substitute part numbers are explicitly confirmed in the provided documentation.
