LTC2862IS8-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2862IS8-1#PBF is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices. It operates on a 3V to 5.5V supply voltage and supports data rates up to 20Mbps. The device features ±60V overvoltage fault protection on interface pins during all modes, including power-down. It provides an extended common mode range of ±25V and enhanced ESD protection rated at ±15kV HBM on interface pins. Packaged in an 8-lead SOIC (S8), it functions within an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±60V overvoltage fault protection on transmission lines for robust operation in electrically noisy environments
• Extended ±25V common mode input range with guaranteed failsafe receiver operation under open or shorted bus conditions
• High input impedance supporting up to 256 nodes on the network bus
• Enhanced electrostatic discharge protection with ±15kV HBM rating on interface pins

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 'I' confirms the -40°C to +85°C industrial temperature grade. Confirm the 'S8' package designation matches the required 8-lead plastic SOIC footprint. Ensure the '#PBF' indicates lead-free finish compliance. Cross-reference the datasheet revision to confirm pinout compatibility with existing LT1785 or LT1791 designs if applicable.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed 20Mbps communication with significant ground loop voltages. The half-duplex configuration suits standard RS-485 multi-drop networks. Consider the thermal shutdown feature for protection against excessive power dissipation. Verify that the 3V to 5.5V VCC range aligns with the system power rails.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of low-power transceivers. The IS8-1 variant specifically denotes the industrial temperature grade and 8-lead SOIC package. It is pin-compatible with legacy parts like the LT1785 and LT1791, facilitating direct upgrades for improved fault tolerance.

Drivers, Receivers, Transceivers Replacement Considerations

LT1785 and LT1791 are confirmed pin-compatible replacements offering similar functionality but without the integrated ±60V fault protection.
