LTC2864MPS-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2864MPS-2#TRPBF is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply voltage and supports a maximum data rate of 250kbps in the low EMI slew-rate limited mode. The device features ±60V fault protection on transmission lines, an extended common-mode range of ±25V, and ±15kV ESD protection on interface pins. It utilizes a 14-lead plastic SOIC package and is rated for military-grade operation from -55°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on data lines during all operational modes
• Features fully balanced differential receiver thresholds for low duty cycle distortion
• Includes high input impedance supporting up to 256 nodes on the bus
• Offers current-limited drivers with thermal shutdown protection
