LTC2862AIDD-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2862AIDD-2#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 a maximum data rate of 250kbps with slew-rate limiting for low EMI. 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 ESD on A/B pins. The component utilizes an 8-lead DFN (3mm × 3mm) package with an exposed pad connected to GND. It includes enhanced receiver noise immunity, guaranteed failsafe operation, and an extended common mode range of ±25V.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±60V overvoltage fault protection on interface pins across all operational states
• Slew-rate limited transmission at 250kbps to minimize electromagnetic interference
• Robust electrostatic discharge protection meeting Level 4 IEC standards on bus lines
• Guaranteed failsafe receiver output logic state under open or shorted line conditions

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA) networks
• Industrial control and instrumentation systems
• Building automation and security infrastructure
• HVAC system communication interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing components. Confirm the IDD variant designation corresponds to the 250kbps slew-limited specification rather than the high-speed alternative. Ensure the DFN package thermal pad connection requirements are addressed in the layout design to maintain optimal performance and reliability.

Drivers, Receivers, Transceivers Selection Notes

Select this model specifically for applications requiring low electromagnetic emissions due to its slew-rate limited driver characteristics. The 250kbps speed option distinguishes it from the LTC2862A-1 variant which supports higher speeds up to 20Mbps. Consider the DFN package form factor for space-constrained designs while ensuring adequate thermal management through the exposed pad connection.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862A family of robust RS485/RS422 transceivers. The -2 suffix identifies the specific version optimized for lower data rates with enhanced noise filtering and slew-rate limiting. It serves as an upgrade to previous generations by offering improved ESD tolerance and fault protection without requiring external protection circuitry.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2862AIDD-1#TRPBF offers identical pinout and packaging but supports data rates up to 20Mbps without slew-rate limiting.
