LTC2852CS#PBF

Drivers, Receivers, Transceivers Overview

The LTC2852CS#PBF 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 tolerance of ±15kV HBM. Supply currents are typically 370µA in receive mode and 450µA in transmit mode. It operates within the commercial temperature range of 0°C to 70°C and is housed in a 14-pin SO package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex architecture with independent driver and receiver channels
• High input impedance receiver supports extensive multinode networks
• Integrated failsafe logic ensures defined output states during idle conditions
• Robust protection against overcurrent, thermal overload, and electrostatic discharge

Drivers, Receivers, Transceivers Applications

• Low power RS-485/RS-422 communication interfaces
• Multinode industrial network level translators
• Backplane transceiver systems

Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix matches the required specifications. Confirm the package type corresponds to the design requirements. Ensure the temperature grade aligns with the operational environment. Check for lead-free compliance if necessary. Validate the manufacturer identification before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex communication at speeds up to 20Mbps. It is suitable for environments needing high node density due to its low unit load characteristic. Consider the commercial temperature range limits when designing for extreme conditions. Evaluate the need for failsafe protection in unpowered or floating bus scenarios.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2850/LTC2851/LTC2852 family of low-power transceivers. While the LTC2850 offers half-duplex functionality and the LTC2851 provides full-duplex without enables, the LTC2852 specifically integrates enable controls for both the driver and receiver. This allows for precise management of transmission states and power consumption in complex bus topologies.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2852CS#TRPBF serves as a tape-and-reel alternative to the tube-packaged LTC2852CS#PBF. Both variants share identical electrical characteristics and pin configurations, differing only in packaging format.
