LTC2862CS8-2#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862CS8-2#PBF is a half-duplex RS485/RS422 transceiver housed in an 8-lead SOIC package. It operates on a 3V to 5.5V supply and supports data rates up to 20Mbps or low EMI 250kbps. The device features ±60V overvoltage fault protection on interface pins, ±15kV ESD protection, and an extended common mode range of ±25V. It includes one driver and one receiver with guaranteed failsafe operation, current-limited drivers, thermal shutdown, and operates within a commercial temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults to ±60V during all modes including power-down
• Enhanced ESD protection withstands ±15kV HBM on interface pins without latchup
• Extended common mode range of ±25V improves reliability in electrically noisy environments
• Guaranteed failsafe receiver operation ensures logic high state when inputs are open or shorted

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA)
• Industrial control and instrumentation networks
• Building automation, security systems, and HVAC
• Medical equipment
• Lighting and sound system control

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CS8-2' confirms the commercial temperature grade (0°C to 70°C), half-duplex configuration, and 250kbps slew-rate limited data rate. Confirm the '#PBF' designation indicates lead-free finish and RoHS compliance. Ensure the SOIC-8 package matches the PCB footprint requirements for the target design.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault tolerance against large ground loop voltages and line faults up to ±60V. The 250kbps mode is suitable for reducing electromagnetic interference in sensitive industrial environments. Verify that the single driver/receiver architecture fits the network topology needs compared to full-duplex alternatives like the LTC2863.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of low-power RS485/RS422 transceivers. It is pin-compatible with legacy parts such as the LT1785 and LT1791, facilitating direct upgrades in existing designs. The CS8 variant specifically denotes the commercial temperature range within the broader product line.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2862IS8-2#PBF offers the same electrical specifications but extends the operating temperature range to –40°C to 85°C.
