LTC2856HMS8-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2856HMS8-1#TRPBF is a low-power, half-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a single 4.5V to 5.5V supply and supports maximum data rates of 20Mbps. The device features enhanced ESD protection capable of withstanding ±15kV (Human Body Model) without latchup or damage. It incorporates current-limited drivers and thermal shutdown for fault protection. The receiver input resistance exceeds 96kΩ in C and I grades, representing a one-eighth unit load that supports up to 256 nodes per bus. The component includes a failsafe feature ensuring a high output state during floating or shorted inputs.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced electrostatic discharge protection withstands ±15kV human body model stress without latchup or damage.
• High input impedance receiver design supports up to 256 nodes on the bus line.
• Integrated thermal shutdown and current limiting protect against excessive power dissipation from bus contention.
• Guaranteed failsafe operation ensures a logic-high receiver output when inputs are floating or shorted.

Drivers, Receivers, Transceivers Applications

• Low electromagnetic interference industrial communication networks
• Multipoint backplane transceiver systems
• Level translation interfaces between different voltage domains

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging rather than tube packaging. Confirm the H-grade designation matches the required -40°C to +125°C operating temperature range for your application environment. Ensure the MSOP-8 package type aligns with your PCB footprint requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring high-speed 20Mbps data transmission with robust fault protection. The H-grade variant is necessary for environments exceeding standard commercial temperature limits. Verify that the half-duplex configuration meets the system's communication direction requirements compared to full-duplex alternatives.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2856 family of rugged RS485/RS422 transceivers. It shares architectural similarities with the LTC2857 and LTC2858 series but is distinctively configured as a half-duplex device. The family emphasizes low power consumption and high node count capabilities within a compact surface-mount package.
