LTC2862AHDD-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2862AHDD-1#TRPBF is a low-power, half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply and supports data rates up to 20Mbps. The device features ±60V overvoltage fault protection on interface pins during all modes, including power-down. It provides ±40kV HBM ESD protection on A/B pins and Level 4 IEC ESD/EFT compliance. Packaged in an 8-lead (3mm × 3mm) Plastic DFN with an exposed pad connected to GND, it functions within a temperature range of –40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Robust ±60V overvoltage fault tolerance on interface pins across all operational states
• High-level electromagnetic immunity with ±40kV HBM ESD and Level 4 IEC ESD/EFT protection
• Guaranteed failsafe receiver operation with fully balanced differential thresholds for low duty cycle distortion
• Extended common mode input range of ±25V for reliable communication in noisy environments

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
• Medical equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the AHDD designation corresponds to the automotive-grade temperature range of –40°C to +125°C. Ensure the ordering information matches the required package type and lead finish specifications provided in official documentation.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed data transmission up to 20Mbps alongside significant electrical noise immunity. The extended common mode range and robust fault protection make it suitable for industrial environments with large ground loop voltages. Verify that the 8-lead DFN package dimensions fit the target PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862A family of RS-485/RS-422 transceivers. It is pin-compatible with the standard LTC2862 and LT1785 devices. The 'H' grade denotes an extended operating temperature range compared to commercial or industrial grades, while the 'D' indicates the DFN package style.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC2862AIDD-1#TRPBF serves as a functional substitute but operates within a limited industrial temperature range of –40°C to +85°C rather than the extended range of the AHDD variant.
