LTC2858CMS-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2858CMS-2#TRPBF is a low-power, full-duplex RS485/RS422 transceiver operating on a 5V supply. It features a maximum data rate of 250kbps with slew-rate limiting for low EMI emissions. The device includes independent driver and receiver enable controls (DE and RE). It supports up to 256 nodes per bus due to its one-eighth unit load receiver input resistance (>96kΩ). Enhanced ESD protection withstands ±15kV HBM without latchup. The component operates within a commercial temperature range of 0°C to 70°C and is housed in a 10-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate limited driver outputs reduce high-frequency EMI emissions for compliance in sensitive environments.
• High input impedance receiver allows connection of up to 256 nodes on the bus while maintaining failsafe operation.
• Independent driver and receiver enables provide flexible power management and bus control capabilities.

Drivers, Receivers, Transceivers Applications

• Low EMI industrial communication networks
• Backplane transceiver interfaces
• Level translation between different voltage domains

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing this component. Confirm the 'C' grade designation matches the required commercial temperature range of 0°C to 70°C for your application environment. Ensure the 10-lead MSOP footprint aligns with your PCB layout constraints before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this model over the LTC2858-1 variant if minimizing electromagnetic interference is a priority, as the -2 suffix indicates a 250kbps slew-rate limited version. Verify that the full-duplex architecture with separate enable pins meets your system's control logic requirements compared to half-duplex alternatives.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC285x family of low-power RS485/RS422 transceivers from Analog Devices. The family shares common features such as 15kV ESD protection and thermal shutdown, but varies by duplex mode and data rate specifications. The LTC2858 specifically provides full-duplex communication with individual driver and receiver control.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2858IMS-2#PBF offers identical electrical performance in an MSOP-10 package but is supplied in tube format rather than tape and reel.

Drivers, Receivers, Transceivers FAQ

What is the maximum data rate for the LTC2858CMS-2?
