LTC2852CMS#PBF

Drivers, Receivers, Transceivers Overview

The LTC2852CMS#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 and includes failsafe logic for floating inputs. The device provides ±15kV HBM ESD protection, current-limited drivers, and thermal shutdown. Supply currents are typically 370µA in receive mode and 450µA in transmit mode. It 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

• Full-duplex operation with independent driver and receiver channels
• High input impedance receiver supports extensive multinode bus configurations
• Integrated overcurrent limiting and thermal shutdown for fault protection
• Glitch-free power-up/down driver outputs ensure signal integrity

Drivers, Receivers, Transceivers Applications

• Low power RS-485/RS-422 communication networks
• Level translation between different voltage domains
• Backplane interface applications requiring high node counts

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CMS' corresponds to the 10-lead MSOP package and commercial temperature grade. Confirm the '#PBF' designation indicates lead-free compliance. Cross-reference the manufacturer's official ordering guide to ensure the exact part number matches your required packaging and environmental specifications before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside low power consumption. It is suitable for systems needing high node density due to its one-eighth unit load receiver. Ensure the application environment remains within the 0°C to 70°C commercial range. Consider higher temperature grades if ambient conditions exceed these limits.

Drivers, Receivers, Transceivers Part Context

This device belongs to the LTC285x family of 3.3V, 20Mbps transceivers from Analog Devices. It complements the half-duplex LTC2850 and the enable-less full-duplex LTC2851. The family shares common electrical characteristics but differs in duplex capability and control pin availability for power management.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the LTC2852CS (SO-14 package) and LTC2852MS (DFN-10 package). Verify that any replacement maintains the same full-duplex functionality and package footprint compatibility.
