LTC2851MPS8#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2851MPS8#TRPBF is a full-duplex RS-422/RS-485 transceiver operating on a single 3.3V supply (3V to 3.6V). It supports data rates up to 20Mbps with typical receive mode current of 370µA and transmit mode current of 450µA. The device features a high input impedance receiver exceeding 96kΩ, supporting up to 256 nodes per bus. It includes failsafe logic ensuring a high output state during floating or shorted inputs. Protection mechanisms include ±15kV HBM ESD tolerance, driver current limiting, and thermal shutdown. The component operates within the military temperature range of -55°C to +125°C and is housed in an 8-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation with independent transmitter and receiver channels
• High input impedance receiver supporting up to 256 nodes on the bus
• Integrated failsafe logic guarantees a high output state for unpowered or floating inputs
• Robust protection against electrostatic discharge and excessive power dissipation

Drivers, Receivers, Transceivers Applications

• Multinode industrial communication networks
• Backplane transceivers requiring low power consumption
• Level translation between different voltage domains
• Harsh environment instrumentation with extended temperature requirements

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing components. Confirm that the MP grade designation corresponds to the required military temperature range specifications for your application environment. Ensure compatibility with standard RS-485/RS-422 signaling protocols before integration into existing system architectures.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring simultaneous bidirectional communication without separate enable pins for the driver and receiver. Consider the 8-lead MSOP package for space-constrained designs. Evaluate the 20Mbps maximum data rate against network latency requirements. Verify that the 3.3V supply voltage aligns with the system power distribution plan.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC285x family of low-power transceivers. Unlike the half-duplex LTC2850, the LTC2851 provides full-duplex capability. It shares similar electrical characteristics with the LTC2852 but lacks the dedicated enable pins found in the latter. The MP suffix denotes the military-grade temperature variant, distinguishing it from commercial and industrial grades.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC2851IS8#PBF serves as a direct functional substitute offering identical electrical performance in an SOIC-8 package. For lead-free compliance verification, ensure the #PBF suffix is present on any replacement units to maintain environmental standards.
