LTC2852MPMS

Drivers, Receivers, Transceivers Overview

The LTC2852MPMS is a high-speed RS-485/RS-422 transceiver manufactured by Analog Devices Inc., designed for operation with a single 3.3V supply voltage. It supports data transmission rates up to 20Mbps and features an eight-unit load receiver, enabling the connection of up to 32 nodes on a single bus. The device incorporates fail-safe circuitry that ensures a high logic level at the receiver output when inputs are floating or shorted. Packaged in an 8-lead MSOP format, it operates within a temperature range of -55°C to +125°C and draws a typical quiescent current of 450µA.

Drivers, Receivers, Transceivers Feature Summary

• Supports RS-485 and RS-422 communication standards with high-speed data transfer capabilities.
• Integrates fail-safe mechanisms to maintain a defined high output state during input disconnection or shorting.
• Features an eight-unit load receiver architecture to maximize network node density.

Drivers, Receivers, Transceivers Applications

• Industrial automation control networks requiring robust multi-drop communication.
• Building automation systems utilizing RS-485 bus topologies.
• Metering applications involving serial data transmission over long distances.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure the component meets required environmental certifications for the target deployment region. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability status and lead times prior to procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring half-duplex communication with moderate node counts. The eight-unit load specification limits the total addressable devices per bus segment compared to higher-load variants. Verify that the system power supply remains stable at 3.3V to ensure signal integrity at the maximum 20Mbps data rate without excessive jitter.

Drivers, Receivers, Transceivers Part Context

This device belongs to the LTC2851/LTC2852 family of rugged transceivers optimized for 3.3V operation. It serves as a direct interface between microcontrollers and differential bus lines. The MPMS suffix indicates a military-grade or extended industrial qualification variant housed in a compact surface-mount package suitable for space-constrained PCB layouts.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC2850MPMS offers similar electrical characteristics but may differ in specific pinout configurations or loading capabilities. The LTC2851MPMS provides comparable performance with potential variations in ESD protection levels. Confirm functional compatibility through detailed datasheet comparison before substitution.
