LTC2858HDD-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2858HDD-1#PBF is a low power, full-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a 5V supply and supports a maximum data rate of 20Mbps. The device features a one-eighth unit load receiver input resistance exceeding 96kΩ, enabling support for up to 256 nodes per bus. It includes enhanced ESD protection rated at ±15kV (human body model) on interface pins without latchup or damage. The component incorporates current-limited drivers and thermal shutdown to prevent excessive power dissipation during bus contention. It guarantees failsafe receiver operation over the entire common mode range and maintains high output impedance when disabled.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication capability with independent driver and receiver control
• Enhanced electrostatic discharge protection rated at ±15kV HBM on interface pins
• High input impedance receiver supporting up to 256 nodes on the bus
• Integrated thermal shutdown and current limiting for fault protection

Drivers, Receivers, Transceivers Applications

• Low power RS485/RS422 transceiver networks
• Level translator applications
• Backplane transceiver systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free design and RoHS compliance as documented in official Analog Devices materials. Confirm the package type DD corresponds to the 10-lead DFN form factor. Ensure the temperature grade matches the required operational environment specifications before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex RS485 or RS422 communication at speeds up to 20Mbps. The high input impedance allows for extensive node counts on a single bus segment. Consider the thermal and current protection features for environments prone to bus faults or contention.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC285x family of low power transceivers from Analog Devices. The family includes half-duplex variants like the LTC2856 and other full-duplex options such as the LTC2857. The specific designation -1 indicates the 20Mbps speed grade, while the DD suffix specifies the 10-lead plastic DFN package.
