LTC2862AIDD-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2862AIDD-1#TRPBF is a low-power, half-duplex RS485/RS422 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 Level 4 IEC ESD protection and ±40kV HBM protection on the A and B pins. The component utilizes an 8-lead DFN package with dimensions of 3mm x 3mm and includes thermal shutdown and current-limited drivers.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±60V overvoltage fault protection on interface pins for robust operation in electrically noisy environments
• High-level electrostatic discharge immunity with Level 4 IEC ESD and ±40kV HBM protection on bus lines
• Extended common mode range of ±25V to support large ground loop voltages
• Guaranteed failsafe receiver operation with fully balanced differential thresholds for low duty cycle distortion

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing components. Confirm that the IDD designation corresponds to the industrial temperature grade of –40°C to +85°C. Ensure compatibility with the required PCB footprint for the 8-lead DFN package before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring high-speed data transmission up to 20Mbps alongside significant fault tolerance. The device is suitable for designs needing extended common mode voltage handling without external protection components. Consider the DFN package size if board space is constrained compared to SOIC alternatives.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862A family of ruggedized transceivers. It is pin-compatible with the earlier LTC2862 and LT1785 models, facilitating direct upgrades or replacements in existing designs. The '1' suffix indicates the high-speed 20Mbps variant, distinct from the slew-rate limited 250kbps option.
