LTC2862ACDD-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2862ACDD-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 data rates up to 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 (±8kV contact) and ±40kV HBM protection on A/B pins. The component utilizes an 8-lead DFN package (3mm × 3mm) with an exposed pad connected to GND. It operates within a temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±60V overvoltage fault protection on interface pins across all operational states
• Robust electrostatic discharge immunity meeting Level 4 IEC standards and ±40kV HBM ratings
• Slew-rate limited transmission at 250kbps to minimize electromagnetic interference emissions
• Extended common mode input range spanning ±25V for reliable operation in noisy environments

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 rather than tube packaging when sourcing components. Confirm the AC grade designation corresponds to the commercial operating temperature range of 0°C to 70°C. Ensure the DFN package dimensions align with the target PCB footprint requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring low electromagnetic interference due to its 250kbps slew-rate limited data rate option. Choose this variant over the -1 version when noise immunity and reduced emissions are prioritized over high-speed throughput. Verify that the 0°C to 70°C commercial temperature range meets the environmental specifications of the intended deployment location.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862A family of robust RS485/RS422 transceivers. It shares pin compatibility with the standard LTC2862 and LT1785 devices. The -2 suffix indicates the 250kbps slew-rate limited configuration, distinguishing it from the high-speed 20Mbps -1 variant within the same package and feature set.
