LTC2858IMS-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2858IMS-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 for up to 256 nodes per bus in C and I-grade variants. Key electrical parameters include a maximum shutdown current of 5µA for C/I grades, a receive mode supply current of up to 900µA, and driver short-circuit current limits of ±250mA. The component includes thermal shutdown protection and guaranteed failsafe receiver operation over the entire common-mode range.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements and signal integrity standards before integration. Cross-reference part markings with datasheet specifications to authenticate components.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex operation with high noise immunity. Consider the IMS-1 suffix for industrial temperature ranges and MSOP-10 packaging. Evaluate power consumption constraints against the specified supply currents in receive and transmit modes.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2858 family of low-power transceivers designed for reliable serial communication. It complements half-duplex variants like the LTC2856 and non-enable full-duplex models such as the LTC2857 within the Analog Devices portfolio.
