LTC2862ACDD-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2862ACDD-1#TRPBF 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 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 protection on the A and B pins. The component utilizes an 8-lead (3mm × 3mm) Plastic DFN package with an exposed pad connected to GND. It is rated for commercial operating temperatures from 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 with Level 4 IES ESD and ±40kV HBM ratings on bus lines
• Extended common mode input range supporting voltages from -25V to +25V
• 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 #TRPBF indicates tape and reel packaging rather than tube packaging. Confirm the AC grade designation corresponds to the 0°C to 70°C commercial temperature range required for the target application environment. Ensure the DFN package footprint matches the PCB layout specifications provided in the datasheet.

Drivers, Receivers, Transceivers Selection Notes

Select this variant for applications requiring standard 20Mbps data transmission speeds within commercial temperature limits. Consider the LTC2862A-2 option if lower electromagnetic interference is prioritized over maximum speed. Verify that the system ground loop voltages remain within the extended ±25V common mode range to ensure reliable communication without external protection components.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862A family of robust RS-485/RS-422 transceivers. It serves as an improved version of the LTC2862, offering enhanced ESD protection and noise immunity. The part is pin-compatible with the original LTC2862 and LT1785 devices, facilitating direct upgrades in existing designs requiring higher fault tolerance.
