LTC2862MPS8-2#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862MPS8-2#PBF is a half-duplex RS-485/RS-422 transceiver in an 8-lead SOIC package. It operates on a 3V to 5.5V supply with a logic-selectable data rate of either 20Mbps or low EMI 250kbps. The device features ±60V overvoltage fault protection on interface pins during all modes, including power-down. It supports an extended common mode range of ±25V and includes ±15kV HBM ESD protection on interface pins. The MP-grade variant ensures reliable operation across an industrial temperature range of –55°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults up to ±60V
• Guaranteed failsafe receiver operation with high input impedance supporting 256 nodes
• Fully balanced differential receiver thresholds for low duty cycle distortion
• Current limited drivers and thermal shutdown protection

• Supervisory Control and Data Acquisition (SCADA)
• Industrial control and instrumentation networks
• Automotive and transportation electronics
• Building automation, security systems, and HVAC
• Medical equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix MPS8 indicates the military/industrial grade (-55°C to 125°C) and S8 denotes the 8-lead plastic SOIC package. Confirm the -2 suffix corresponds to the 250kbps slew-rate-limited data rate option. Ensure the #PBF designation confirms lead-free and RoHS compliance status before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing RS-485 links requiring robust fault tolerance against large ground loop voltages. The 250kbps mode is suitable for applications prioritizing low electromagnetic interference over maximum throughput. Verify that the 8-pin SOIC footprint aligns with the PCB layout constraints and that the half-duplex architecture meets the system's communication requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862 family of low-power transceivers designed for harsh electrical environments. It shares pin compatibility with legacy parts like the LT1785 and LT1791, facilitating direct upgrades. The MPS8 suffix specifically identifies the extended temperature range version within the standard SOIC-8 package lineup.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly states the device is pin compatible with the LT1785 and LT1791. Designers replacing these older components should verify that the new ±60V fault protection capabilities do not conflict with existing circuit protection schemes.
