LTC2862IS8-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2862IS8-1#TRPBF 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 maximum data rate of 20Mbps. The device features ±60V fault protection and an extended common mode range of ±25V. Interface pins provide ±15kV ESD protection. It includes guaranteed failsafe receiver operation, current-limited drivers, and thermal shutdown. The operating temperature range is -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on interface pins during all operational modes, including power-down.
• Features enhanced ESD protection rated at ±15kV HBM on interface pins and ±8kV on other pins.
• Supports up to 256 nodes on the bus due to high input impedance and guarantees failsafe receiver operation.

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA) systems
• Industrial control and instrumentation networks
• Automotive and transportation electronics

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the IS grade designation corresponds to the required industrial temperature range for the target application environment. Ensure compatibility with existing PCB footprints for the 8-lead SOIC package.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault tolerance against line faults and ground loop voltages. The half-duplex configuration is suitable for bidirectional communication where simultaneous transmission is not required. Consider the 20Mbps speed capability for high-throughput industrial protocols.

Drivers, Receivers, Transceivers FAQ

Does the device maintain fault protection when powered off?

Yes, the ±60V fault protection remains active on the A and B pins even when the VCC supply is removed or the device is in shutdown mode.

What is the differential input threshold voltage?

The differential input signal threshold voltage is typically ±200mV, ensuring reliable detection of valid signals while providing noise immunity through hysteresis.
