ADM4853ARZ

Drivers, Receivers, Transceivers Overview

The ADM4853ARZ is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. It supports data rates up to 10 Mbps and operates on a single 5 V power supply. The device features slew rate limiting to reduce electromagnetic interference (EMI) and includes true fail-safe receiver inputs that ensure a logic high output when inputs are open or shorted. It offers a shutdown mode with a maximum supply current of 5 µA. The component is specified for operation over an industrial temperature range from −40°C to +85°C and is available in an 8-lead LFCSP package.

Drivers, Receivers, Transceivers Feature Summary

• Slew rate limited driver outputs designed to minimize electromagnetic interference (EMI) and reduce data errors caused by reflections.
• True fail-safe receiver inputs guarantee a known logic high state when differential inputs are open, shorted, or disconnected.
• High input impedance allows connection of up to 256 transceivers on a single bus while maintaining compatibility with standard unit loads.
• Low power shutdown mode reduces supply current to a maximum of 5 µA when the device is disabled.

Drivers, Receivers, Transceivers Applications

• EMI sensitive systems requiring controlled signal edge rates
• Industrial control networks utilizing multipoint bus topologies
• DTE to DCE interfaces supporting high-speed half-duplex communication

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and automotive qualification requirements if applicable to the target environment. Ensure the procurement source provides valid traceability for the Analog Devices manufacturer part number.

Drivers, Receivers, Transceivers Selection Notes

Select the ADM4853ARZ for applications requiring 10 Mbps half-duplex communication with reduced EMI emissions. Compare against the ADM4857 for full-duplex variants or other speed options within the family. Verify that the 8-lead LFCSP package fits the board layout constraints and thermal requirements of the design.

Drivers, Receivers, Transceivers Part Context

The ADM4853ARZ belongs to the ADM4850 through ADM4857 series of 5 V RS-485/RS-422 transceivers. This family differentiates devices primarily by duplex mode and data rate capabilities. The ADM4853 specifically addresses the need for high-speed half-duplex transmission with integrated EMI suppression features suitable for noisy industrial environments.
