LTC2864IDD-2#PBF

Drivers, Receivers, Transceivers Overview

The LTC2864IDD-2#PBF is a low-power, full-duplex RS-485/RS-422 transceiver manufactured by Analog Devices. It operates on a 3V to 5.5V supply voltage and supports a maximum data rate of 250kbps in its low EMI slew-rate limited mode. The device features ±60V fault protection on the transmission lines during all operational modes, including power-down. It provides ±15kV ESD protection on interface pins and an extended common-mode input range of ±25V. Packaged in a 10-lead (3mm × 3mm) plastic DFN with an exposed pad connected to PCB ground, it is rated for operation from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced ESD protection with ±15kV HBM rating on interface pins
• Guaranteed failsafe receiver operation with fully balanced thresholds

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure the component matches the required duplex configuration and data rate specifications for the target application before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring full-duplex communication with robust fault tolerance. The IDD suffix indicates an industrial temperature range (-40°C to +85°C) and a DFN package. Verify compatibility with existing logic levels and ensure adequate thermal management for the small footprint.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC286x family of fault-protected transceivers. It shares pinout compatibility with legacy parts like the LT1785 and LT1791 but offers superior overvoltage protection and ESD resilience. The '2' suffix denotes the 250kbps low EMI variant within the full-duplex LTC2864 series.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2864IS-2#PBF: Same electrical performance in a 14-lead SOIC package. LTC2864MPS-2#PBF: Military-grade version with extended temperature range (-55°C to +125°C).

Drivers, Receivers, Transceivers FAQ

Does the LTC2864IDD-2#PBF support high-speed data rates?

No, the '-2' suffix indicates the low EMI 250kbps slew-rate limited mode. High-speed 20Mbps operation is available in the '-1' variants.

What is the common-mode input voltage range?

The device supports an extended common-mode range of -25V to +25V, allowing operation in environments with large ground loop voltages.

How is the exposed pad handled in the DFN package?

Pin 11 is the exposed pad and must be connected to PCB ground for proper thermal dissipation and electrical functionality.
