LTC2856HMS8-2#PBF

Drivers, Receivers, Transceivers Overview

The LTC2856HMS8-2#PBF is a low-power, half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. It operates on a single 5V supply and supports a maximum data rate of 250kbps to minimize electromagnetic interference (EMI). The device features a one-eighth unit load receiver input resistance exceeding 96kΩ, 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.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate limited driver outputs designed to control high-frequency EMI emissions
• Guaranteed failsafe receiver operation ensuring a logic-high state during floating or shorted inputs
• High input impedance allowing connection of up to 256 nodes on the communication bus

Drivers, Receivers, Transceivers Applications

• Low EMI industrial communication networks
• Backplane transceiver systems
• Level translation interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure the part number matches the required duplex mode and data rate specifications for the target application design.

Drivers, Receivers, Transceivers Selection Notes

Select this model when EMI reduction is critical, as the slew-rate limiting restricts the data rate to 250kbps. Choose this variant over the -1 series if lower noise emissions are prioritized over higher throughput speeds.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC285x family of low-power RS-485/RS-422 transceivers. It shares architectural similarities with the LTC2857 and LTC2858 series but is distinctively configured as a half-duplex device with enable controls.
