LTC2852HMS#PBF

Drivers, Receivers, Transceivers Overview

The LTC2852HMS#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 protection rated at ±15kV HBM. It operates within a temperature range of -40°C to +125°C (H-grade) and draws a typical receive mode current of 370µA.

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 ensuring high output state during idle or fault conditions
• Robust protection against overcurrent, thermal overload, and electrostatic discharge

Drivers, Receivers, Transceivers Applications

• Low power RS-485/RS-422 transceivers
• Level translator circuits
• Backplane transceiver systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free construction when sourcing this component. Confirm that the 'H' grade designation matches the required automotive temperature range of -40°C to +125°C for your application environment. Ensure the MSOP-10 package footprint aligns with your PCB layout constraints before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC2852 over half-duplex variants when simultaneous bidirectional communication is required. This model provides separate transmit and receive paths, unlike the LTC2850. Consider the H-grade specification if deployment in high-temperature environments exceeding 85°C is necessary. Verify that the 3.3V supply voltage meets system requirements as the device is not optimized for 5V operation.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC285x family of low-power interface ICs manufactured by Analog Devices. It shares architectural similarities with the LTC2850 and LTC2851 but distinguishes itself through full-duplex functionality. The family is designed for applications requiring robust serial communication with minimal power consumption and high noise immunity in industrial settings.
