LTC2862AIDD-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2862AIDD-1#PBF 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 voltage 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 ESD on interface pins. The component utilizes an 8-lead DFN package with dimensions of 3mm x 3mm and operates within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±60V overvoltage fault protection on A and B pins for robust operation in electrically noisy environments
• High-level electrostatic discharge immunity with ±40kV HBM and Level 4 IES ESD protection on interface pins
• Extended common mode input range of ±25V to accommodate large ground loop voltages
• Guaranteed failsafe receiver operation ensuring logic high output when inputs are open or shorted

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 #PBF indicates tube packaging when sourcing components. Confirm that the IDD suffix corresponds to the industrial temperature grade (-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 model for applications requiring high-speed data transmission up to 20Mbps with significant noise immunity. The integrated fault protection eliminates the need for external transient voltage suppression devices in many scenarios. Consider the thermal characteristics of the exposed pad for proper heat dissipation in dense layouts.
