LTC2852HS#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2852HS#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. It operates within an automotive temperature range of -40°C to +125°C and is housed in a 10-pin MSOP package.

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 a high output state during idle or fault conditions
• Robust protection mechanisms including thermal shutdown and current limiting

Drivers, Receivers, Transceivers Applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix HS#TRPBF against official Analog Devices documentation to confirm the automotive grade temperature rating and tape-and-reel packaging configuration. Ensure compatibility with the required 10-pin MSOP footprint during procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex operation is required alongside high node capacity. The H-grade designation ensures reliable performance across the extended automotive temperature spectrum. Confirm that the 3.3V supply voltage aligns with the system power architecture before integration.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC285x family of low-power interface ICs designed for robust serial communication. It complements half-duplex variants like the LTC2850 by providing simultaneous transmit and receive paths. The series emphasizes low static current consumption while maintaining high-speed data integrity.

Drivers, Receivers, Transceivers FAQ

What is the receiver input resistance for the H-grade version?

The receiver input resistance for the H-grade version is greater than 48kΩ, representing a one-quarter unit load.

How does the device handle bus contention?

Excessive power dissipation from bus contention is prevented by current limiting all outputs and activating thermal shutdown if junction temperatures exceed limits.

Is external pull-up required for the failsafe feature?

No, the receiver output is internally driven high or low, eliminating the need for external pull-up resistors to maintain the failsafe state.
