LTC2856CMS8-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2856CMS8-1#PBF is a low-power, half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices. It operates on a single 5V supply (4.5V to 5.5V) and supports maximum data rates of 20Mbps. The device features enhanced ESD protection capable of withstanding ±15kV human body model discharges without latchup or damage. It incorporates a one-eighth unit load receiver input impedance, allowing up to 256 nodes per bus in the commercial grade. Key electrical parameters include a typical receive mode current of 900µA, driver short-circuit current limit of ±250mA, and thermal shutdown protection. The component is housed in an 8-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced electrostatic discharge protection ensures robust operation against ±15kV HBM events without latchup.
• High input impedance receiver design supports extensive network topologies with up to 256 nodes.
• Integrated thermal shutdown and current limiting protect the device from excessive power dissipation during faults.

Drivers, Receivers, Transceivers Applications

• Industrial automation networks requiring RS-485 communication
• Building automation systems utilizing RS-422 interfaces
• Low electromagnetic interference applications via slew rate limited variants

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade. Ensure the procurement channel provides original manufacturer documentation to validate authenticity. Cross-reference the part number with official Analog Devices databases to confirm availability status and compliance with RoHS standards before finalizing acquisition.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high node density and robust fault protection in half-duplex serial communication environments. Consider the commercial temperature range specifications when evaluating environmental constraints. Verify that the 20Mbps data rate aligns with system timing requirements and that the 5V supply voltage matches the available power rails.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2856 family of low-power transceivers designed for reliable serial communication. It shares architectural similarities with the full-duplex LTC2857 and the enabled full-duplex LTC2858. The CMS8-1 designation specifically identifies the commercial grade variant within the 8-lead MSOP package format, distinguishing it from industrial or automotive grades.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2856CMS8-1#TRPBF offers the same functionality in tape and reel packaging. For full-duplex requirements, consider the LTC2857 series. Industrial temperature range equivalents are available as LTC2856IMS8-1#PBF. Always verify pin compatibility and electrical characteristics before substituting.
