LTC2864CS-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2864CS-1#TRPBF is a full-duplex RS485/RS422 transceiver operating on a 3V to 5.5V supply. It supports a maximum data rate of 20Mbps and features ±60V fault protection on transmission lines during all modes, including power-down. The device includes an extended common mode range of ±25V and ±15kV ESD protection on interface pins. It operates within a commercial temperature range of 0°C to 70°C and is housed in a 14-lead (150mil) Plastic SO package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CS' indicates the commercial temperature grade (0°C to 70°C). Confirm the '#TRPBF' designation corresponds to tape and reel packaging. Ensure the part number matches the 14-lead SOIC footprint required by the design. Cross-reference the manufacturer's latest ordering information to confirm current availability status.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside high-voltage fault tolerance. The 20Mbps data rate suits high-speed industrial networks. Verify that the 14-lead SO package fits the PCB layout constraints. Consider the 3V to 5.5V supply range compatibility with the system logic levels before finalizing the selection.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC286x family of rugged transceivers designed for harsh electrical environments. It shares pinout compatibility with legacy parts like the LT1785 and LT1791. The CS suffix specifically denotes the commercial temperature variant, distinguishing it from industrial or military grade options within the same functional family.

Drivers, Receivers, Transceivers FAQ

Does the LTC2864 support half-duplex operation?

No, the LTC2864 is strictly a full-duplex transceiver. Half-duplex functionality is provided by the LTC2862.

What is the failsafe behavior of the receiver?

The receiver guarantees a logic 1 state at the RO output if the differential input voltage is less than 200mV, ensuring safe idle states even with open or shorted lines.

How does the device handle ground loop voltages?

It supports an extended common mode range of ±25V, allowing reliable operation despite large potential differences between local grounds.
