LTC2858CDD-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2858CDD-1#PBF is a low power, full-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a single 5V supply and supports a maximum data rate of 20Mbps. The device features enhanced ESD protection capable of withstanding ±15kV (human body model) without latchup or damage. It incorporates a one-eighth unit load receiver input impedance, allowing up to 256 nodes per bus for C and I grades. Key electrical parameters include a maximum shutdown current of 5µA, a receive mode current of 900µA maximum, and driver short-circuit current limits of ±250mA. The component includes thermal shutdown and current limiting for fault protection.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication capability with independent transmit and receive channels
• Enhanced electrostatic discharge protection rated at ±15kV human body model
• High input impedance receiver supporting extensive multi-drop network configurations
• Integrated thermal shutdown and current limiting for robust fault protection

• Building automation networks utilizing RS485 or RS422 protocols
• Backplane transceiver interfaces in embedded computing environments

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and temperature grade against project requirements before ordering. Confirm that the 10-lead DFN footprint matches the PCB layout design. Ensure supply voltage constraints align with the specified 5V operation range. Check for any recent product change notifications regarding manufacturing updates.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex operation is required alongside high-speed data transmission up to 20Mbps. Consider the 10-lead DFN package for compact board space utilization. Evaluate the need for failsafe receiver operation in noisy industrial environments. Verify compatibility with system logic levels and common mode voltage ranges.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC285x family of low power RS485/RS422 transceivers from Analog Devices. The family includes half-duplex variants like the LTC2856 and other full-duplex options such as the LTC2857. The -1 suffix indicates the 20Mbps speed grade, distinguishing it from the slew-rate limited -2 variants designed for lower electromagnetic interference applications.
