MAX3074EEPA+

Overview

The MAX3074EEPA+ is a full-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 3.3V supply and features one driver and one receiver. The device supports data transmission rates up to 500kbps with slew-rate-limited drivers. It includes ±15kV ESD protection, fail-safe circuitry, and hot-swap capability. The component is housed in an 8-pin Plastic DIP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Hot-swap input structure prevents false transitions during bus insertion or power-up
• Fail-safe receiver guarantees logic-high output when inputs are open or shorted
• Slew-rate limiting minimizes electromagnetic interference and reflections

Applications

• Industrial Control Systems
• Telecommunications Equipment
• Security Systems
• Instrumentation

Procurement Notes

Verify the specific suffix EEPA against official documentation to confirm the 8-pin PDIP package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through manufacturer datasheets before finalizing procurement orders.

Selection Notes

Select this component for applications requiring full-duplex communication at speeds up to 500kbps. Ensure the design accommodates the 8-pin DIP footprint and operates within the specified 3.3V supply voltage constraints.

Part Context

This part belongs to the MAX3070E–MAX3079E family of high-speed RS-485/RS-422 transceivers. While sharing core features like ESD protection and fail-safe operation, the MAX3074E specifically provides full-duplex functionality with a fixed 500kbps maximum data rate.

Replacement Considerations

The ADM3074EYRZ serves as a functional equivalent offering similar specifications. Verify pin compatibility and package differences between the SOIC and DIP formats before substitution.
