LTC2852MPDD#PBF

Drivers, Receivers, Transceivers Overview

The LTC2852MPDD#PBF is a full-duplex RS-485/RS-422 transceiver operating on a 3V to 3.6V supply with a maximum data rate of 20Mbps. It features one driver and one receiver in an 8-Lead (3mm × 3mm) Plastic DFN package. The device supports military temperature ranges from -55°C to 125°C, draws 370µA typical current in receive mode, and includes delayed micropower shutdown with 5µA maximum current. Enhanced ESD protection withstands ±15kV HBM, and the receiver input resistance exceeds 96kΩ, supporting up to 256 nodes.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation with independent driver and receiver control via DE and RE pins
• High input impedance receiver supporting up to 256 nodes per bus
• Failsafe receiver guarantees high output state during floating or shorted inputs
• Current-limited drivers with thermal shutdown protection against excessive power dissipation

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific MP suffix indicates the military temperature grade (-55°C to 125°C). Confirm the DD suffix corresponds to the 8-lead DFN package. Ensure the #PBF designation confirms lead-free compliance before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex communication with independent enable controls. The MP grade is necessary for environments exceeding standard industrial temperature limits. Verify that the 3.3V supply voltage aligns with system requirements and that the DFN package fits the PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2850/LTC2851/LTC2852 family of low-power transceivers. While the LTC2850 is half-duplex and the LTC2851 lacks enables, the LTC2852 provides full-duplex capability with dedicated driver and receiver enable pins. The MP suffix specifically denotes the extended military temperature range compared to commercial or industrial variants.

Drivers, Receivers, Transceivers FAQ

What is the receiver input resistance?

The receiver input resistance is guaranteed to be 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 when inputs are floating, shorted, or terminated but not driven, across the entire common mode range.

What is the maximum ESD rating?

Enhanced ESD protection allows the device to withstand up to ±15kV using the human body model without latchup or damage.
