MAX3086EPD+

Overview

The MAX3086EPD+ is a full-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply with a typical quiescent current of 375µA. The device supports data rates up to 10Mbps with unrestricted driver slew rates. It features fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. The unit load receiver input impedance allows up to 256 transceivers on the bus. It is housed in a 14-pin Plastic DIP package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Fail-safe circuitry ensures a logic-high receiver output during idle or fault conditions
• High-speed transmission capability supporting data rates up to 10Mbps
• 1/8-unit-load receiver input impedance enables high node density on communication buses

Applications

• RS-422/RS-485 communications networks
• Industrial-control local area networks
• Level translators for digital interfaces

Procurement Notes

Verify the specific suffix 'EPD+' against the manufacturer's official documentation to confirm the exact operating temperature range, pin configuration, and RoHS compliance status. Ensure the selected variant matches the required environmental specifications for the target application before finalizing procurement orders.

Selection Notes

Select this component for applications requiring full-duplex operation at speeds up to 10Mbps. It is suitable for systems needing high bus capacity due to its 1/8-unit-load input impedance. Consider alternative models from the same family if lower data rates or half-duplex functionality better aligns with system requirements.

Part Context

This device belongs to the MAX3080–MAX3089 series of high-speed transceivers designed for RS-485 and RS-422 communication standards. The series offers various configurations including different duplex modes and selectable slew rates to accommodate diverse industrial and commercial interface needs.

Replacement Considerations

The MAX3080 and MAX3083 are pin-compatible alternatives within the same series. Verify functional differences regarding slew rate limitations and data rate capabilities before substituting these parts.
