MAX3083EPD

Overview

The MAX3083EPD is a half-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and supports data rates up to 10 Mbps. The device features fail-safe receiver circuitry that ensures a high logic output when inputs are open. It includes a shutdown mode for low-power applications, reducing supply current to less than 15 µA. The component is housed in a 14-pin DIP package and is rated for operation over an extended temperature range.

Feature Summary

• Fail-safe receiver design prevents false triggering during idle or fault conditions
• Shutdown capability enables significant power reduction in standby states
• Robust ESD protection on all pins enhances reliability in harsh environments

Applications

• Industrial control systems requiring reliable serial communication
• Building automation networks utilizing RS-485 bus topologies
• Metering equipment with strict power consumption constraints

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the source provides valid RoHS compliance certificates if environmental regulations apply to the target assembly. Cross-reference the part number with the latest datasheet revision history to identify any functional updates or manufacturing changes.

Selection Notes

Select this component for designs requiring full RS-422/RS-485 compatibility with a single +5V supply. The 10 Mbps rate suits high-speed data transfer needs within standard bus limitations. Consider the shutdown feature for battery-operated devices where minimizing quiescent current is critical for extending operational life.

Part Context

This device belongs to the Maxim Integrated RS-485/RS-422 transceiver family, known for robust performance in noisy industrial environments. It complements other interface solutions by offering a balance of speed, power efficiency, and ease of integration into microcontroller-based systems without requiring complex external biasing networks.
