LTC2856CMS8-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2856CMS8-2#TRPBF is a low-power, half-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a single 5V supply and supports a maximum data rate of 250kbps with slew-rate limiting to minimize electromagnetic interference. The device features a one-eighth unit load receiver input impedance, enabling support for up to 256 nodes per bus. It includes enhanced ESD protection rated at ±15kV (HBM), current-limited drivers, and thermal shutdown capabilities. The component is housed in an 8-lead MSOP package and is specified for commercial temperature operation ranging from 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate limited driver outputs reduce high-frequency EMI emissions for compliant communication.
• High input impedance receiver design allows connection of up to 256 nodes on a single bus.
• Integrated failsafe mechanism guarantees a logic-high output state during floating or shorted input conditions.

Drivers, Receivers, Transceivers Applications

• Low EMI industrial fieldbus networks
• Multipoint communication systems requiring high node density
• Backplane transceiver interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing. Confirm the C-grade designation aligns with the required commercial temperature range of 0°C to 70°C for your application environment. Ensure compatibility with 5V logic levels before integration.

Drivers, Receivers, Transceivers Selection Notes

Select this model over the -1 variant when minimizing electromagnetic interference is critical, as it limits the data rate to 250kbps. Verify that the half-duplex configuration meets the system's communication requirements. Consider the H-grade if operation beyond 70°C is necessary.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2856 series of rugged RS485/RS422 transceivers. It shares architectural similarities with the LTC2857 and LTC2858 families but is distinct in its half-duplex operation mode. The series emphasizes low power consumption and robust fault protection for industrial environments.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2856CMS8-1#TRPBF offers identical packaging and pinout but provides a higher 20Mbps data rate without slew-rate limiting. LTC2857CMS8-2#TRPBF provides full-duplex capability instead of half-duplex operation while maintaining the same low-speed characteristics.
