LTC2858CDD-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2858CDD-1#TRPBF is a low power, full-duplex RS485/RS422 transceiver operating on a 5V supply. It supports a maximum data rate of 20Mbps and features a one-eighth unit load receiver input resistance exceeding 96kΩ, enabling up to 256 nodes per bus. The device includes enhanced ESD protection rated at ±15kV (HBM) without latchup or damage. It incorporates current-limited drivers with thermal shutdown for fault protection and guarantees failsafe receiver operation over the entire common mode range. The part operates within a commercial temperature range of 0°C to 70°C and is housed in an 8-Lead Plastic DFN package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication capability with independent driver and receiver control
• High input impedance supporting extensive network node density
• Robust protection against electrostatic discharge and short circuits

Drivers, Receivers, Transceivers Applications

• Industrial automation networks requiring high node counts
• Backplane communication systems
• Level translation interfaces between different voltage domains

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing components. Confirm the C-grade designation matches the required commercial temperature range for your application environment. Ensure compatibility with standard RS485 and RS422 signaling protocols before finalizing procurement decisions.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex operation with high noise immunity and robust ESD protection. The 20Mbps data rate suits high-speed industrial communication needs. Verify that the 5V supply requirement aligns with system power rails and that the DFN package fits the available PCB footprint constraints.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC285x family of low power transceivers designed for RS485 and RS422 standards. It shares core architectural features with half-duplex variants like the LTC2856 but provides simultaneous transmit and receive paths. The family emphasizes low EMI and high reliability in electrically noisy environments.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional substitutes include other Analog Devices full-duplex RS485/RS422 transceivers such as the LTC2857 series. Verify pinout compatibility and electrical specifications match before substitution.
