LTC2852CS#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2852CS#TRPBF is a full-duplex RS-485/RS-422 transceiver operating on a 3.3V supply with a maximum data rate of 20Mbps. It features a one-eighth unit load receiver supporting up to 256 nodes per bus and guaranteed failsafe operation for floating or shorted inputs. The device includes current-limited drivers, thermal shutdown protection, and enhanced ESD protection rated at ±15kV HBM. Typical supply currents are 370µA in receive mode and 450µA in transmit mode. It is available in commercial (C-grade) temperature ranges from 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication capability with independent driver and receiver channels
• High input impedance receiver design allowing connection of up to 256 nodes on the bus
• Integrated failsafe logic ensures a high output state during input faults or disconnection
• Robust protection against overcurrent, thermal overload, and electrostatic discharge events

Drivers, Receivers, Transceivers Applications

• Multinode industrial networks requiring high node density
• Backplane communication systems
• Level translation between different voltage domains
• Low power RS-485/RS-422 interface implementations

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing components. Confirm the C-grade designation matches the required commercial temperature range of 0°C to 70°C for the intended application environment. Ensure compatibility with lead-free manufacturing processes as indicated by the PBF marking.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex operation is necessary compared to half-duplex alternatives like the LTC2850. Consider the MSOP-10 or SO-14 package availability based on board space constraints. Evaluate the 20Mbps speed requirement against lower-speed options if power consumption must be further minimized.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC285x family of low-power transceivers alongside the half-duplex LTC2850 and the enable-less LTC2851. All share similar electrical characteristics but differ in duplex mode and control pin configurations. The CS variant specifically denotes the commercial temperature grade within the broader product line.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2852CS#PBF offers identical functionality in tube packaging instead of tape and reel.
