LTC2862IS8-2#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862IS8-2#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 typical shutdown current of 5µA and active current up to 8mA. The device supports a maximum data rate of 250kbps and provides ±60V fault protection on transmission lines. It features ±15kV ESD protection on interface pins, an extended common mode range of ±25V, and guaranteed failsafe receiver operation. Operating temperatures range from -40°C to +85°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 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
• Automotive and transportation electronics
• Building automation, security systems, and HVAC

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'IS8-2' corresponds to the industrial temperature grade (-40°C to +85°C), 8-lead SOIC package, and 250kbps slew-rate limited data rate. Confirm the '#PBF' designation indicates lead-free finish and RoHS compliance. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault protection against large ground loop voltages up to ±60V. The 250kbps data rate is suitable for low EMI requirements where slower transmission speeds are acceptable. Ensure the system operates within the 3V to 5.5V supply range and requires half-duplex communication capabilities compatible with RS-485 standards.

Drivers, Receivers, Transceivers Part Context

This device belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of low-power transceivers. The IS8-2 variant specifically denotes the industrial temperature range and the 250kbps speed option. It shares pin compatibility with legacy parts like the LT1785 and LT1791, facilitating direct upgrades in existing designs requiring higher fault tolerance.

Drivers, Receivers, Transceivers Replacement Considerations

LT1785 and LT1791 are pin-compatible alternatives within the same ecosystem. Verify that replacement parts match the required 250kbps data rate and ±60V fault protection specifications. Check if the alternative supports the necessary operating temperature range and package type for the target application.
