LTC2862HS8-1#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862HS8-1#PBF is a half-duplex RS485/RS422 transceiver 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 during all modes, including power-down. It provides ±15kV ESD protection on interface pins and ±8kV on other pins. The extended common mode range is ±25V with guaranteed failsafe receiver operation. The operating temperature range is –40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on transmission lines across all operational states
• Features enhanced ESD protection rated at ±15kV HBM on interface pins
• Supports extended common mode input voltage range of ±25V for noisy environments
• Includes fully balanced differential receiver thresholds to minimize duty cycle distortion

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix HS8-1 corresponds to the 8-lead plastic SOIC package and the industrial/high-temperature grade (-40°C to +125°C). Confirm the -1 designation indicates half-duplex functionality with shared A/B pins. Ensure the #PBF marking confirms lead-free finish compliance before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high-voltage fault tolerance is required on RS485/RS422 buses. The half-duplex configuration suits applications sharing a single differential pair. The wide supply range accommodates 3.3V and 5V logic systems. Verify that the 20Mbps rate meets system timing requirements compared to lower-speed alternatives.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862 family of rugged transceivers designed for harsh electrical environments. It shares pin compatibility with legacy LT1785 and LT1791 devices, facilitating direct upgrades. The HS variant specifically denotes the high-temperature grade suitable for demanding automotive or industrial settings requiring extended thermal stability.

Drivers, Receivers, Transceivers Replacement Considerations

LT1785 and LT1791 are confirmed pin-compatible replacements within the same product family.
