LTC2852MPS#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2852MPS#PBF is a low-power, full-duplex RS485/RS422 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 over the entire common mode range. The device includes current-limited drivers, thermal shutdown protection, and enhanced ESD protection up to ±15kV HBM. Typical supply currents are 370µA in receive mode and 450µA in transmit mode. It operates within a military temperature range of -55°C to 125°C and is housed in an MSOP-10 package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex architecture with independent driver and receiver channels
• High input impedance receiver supports up to 256 nodes per bus
• Guaranteed failsafe receiver output under floating or shorted input conditions
• Current-limited drivers with thermal shutdown for fault protection

Drivers, Receivers, Transceivers Applications

• Low power RS485/RS422 transceivers
• Level translators
• Backplane transceivers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements and interface standards before integration. Confirm lead-free status and RoHS compliance through manufacturer datasheets.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex communication at speeds up to 20Mbps with low static power consumption. The high input impedance allows for extensive multinode networks. Verify that the MSOP-10 package fits the available PCB space and thermal constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC285x family of 3.3V RS485/RS422 transceivers. It differs from the half-duplex LTC2850 and the enable-less LTC2851 by providing separate driver and receiver control pins (DE and RE) for full-duplex operation. The MP suffix indicates the military temperature grade variant.

Drivers, Receivers, Transceivers FAQ

What is the receiver input resistance?

The receiver input resistance is greater than 96kΩ for C- and I-grade parts, representing a one-eighth unit load.

How does the failsafe feature work?

The failsafe feature guarantees a logic-high receiver output state when inputs are floating, shorted, or terminated but not driven, across the entire common mode range.

What is the maximum ESD protection rating?

The device can withstand up to ±15kV human body model (HBM) on the transceiver interface pins without latchup or damage.
