MAX3086EEPD+

Overview

The MAX3086EEPD+ is a full-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a single +5V supply and supports data rates up to 10Mbps with unrestricted driver slew rates. The device features ±15kV ESD protection on all I/O pins, fail-safe receiver circuitry that guarantees a logic-high output when inputs are open or shorted, and a 1/8-unit-load input impedance allowing up to 256 transceivers on the bus. It is housed in a 14-pin Plastic DIP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Full-duplex communication architecture with dedicated driver and receiver channels
• Fail-safe receiver design ensuring a high logic state during idle or fault conditions
• Robust electrostatic discharge protection rated at ±15kV via Human Body Model
• High-density bus capability supporting up to 256 nodes through reduced input loading

Applications

• RS-422 and RS-485 serial communication networks
• Industrial control local area networks
• EMI-sensitive applications requiring high-speed data transmission

Procurement Notes

Verify the specific suffix 'EPD+' corresponds to the 14-pin Plastic DIP package variant. Confirm the 'E' designation indicates the extended industrial temperature range of -40°C to +85°C. Ensure compatibility with existing PCB footprints for dual-in-line packages before procurement.

Selection Notes

Select this component for full-duplex systems requiring 10Mbps transmission speeds without slew-rate limitations. It serves as a pin-compatible alternative to industry-standard parts like the 75180, offering enhanced ESD protection and fail-safe features while maintaining standard interface compatibility.

Part Context

This part belongs to the MAX3080E–MAX3089E family of high-speed transceivers. Within this series, the MAX3086E specifically provides full-duplex operation with unrestricted slew rates, distinguishing it from half-duplex variants and slew-rate-limited models designed for lower bandwidth applications.

Replacement Considerations

The datasheet explicitly states pin compatibility with the industry-standard 75180 transceiver. Designers may consider this direct replacement for legacy designs requiring upgraded ESD protection and fail-safe characteristics without altering the board layout.
