MAX3080ECPD+

Overview

The MAX3080ECPD+ is a full-duplex RS-485/RS-422 transceiver in a 14-pin Plastic DIP package. It operates within a 4.75V to 5.25V supply range and supports data rates up to 115kbps with slew-rate limiting. The device features ±15kV ESD protection on I/O pins, fail-safe circuitry ensuring a logic-high receiver output when inputs are open or shorted, and a low-current shutdown mode drawing 1nA. It accommodates up to 256 transceivers on the bus and functions across an industrial temperature range of 0°C to +70°C.

Feature Summary

• Fail-safe receiver guarantees a logic-high output when inputs are open or shorted
• Slew-rate-limited drivers minimize electromagnetic interference and signal reflections
• Enhanced electrostatic discharge protection rated at ±15kV on all I/O pins
• Low-power shutdown mode reduces quiescent current consumption significantly

Applications

• RS-422 and RS-485 communication networks
• EMI-sensitive industrial control applications
• Local area network interconnects
• Level translation between microprocessors and serial buses

Procurement Notes

Verify the specific suffix CPD confirms the 14-pin Plastic DIP package and the 0°C to +70°C commercial temperature range. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications for your assembly process.

Selection Notes

Select this component for full-duplex applications requiring error-free transmission up to 115kbps. Ensure the system environment remains within the specified 0°C to +70°C operating limits. Verify that the 14-pin DIP footprint matches the target PCB layout requirements.

Part Context

This part belongs to the MAX3080E–MAX3089E family of high-speed transceivers designed for RS-485/RS-422 standards. The MAX3080E variant specifically provides full-duplex operation with reduced slew rates. It serves as a pin-compatible alternative to industry-standard devices like the 75180 while offering enhanced ESD protection and fail-safe capabilities.

Replacement Considerations

The datasheet notes pin compatibility with the 75180. Designers should verify that the additional features implemented via pins 1, 6, 8, and 13 do not conflict with existing board designs when substituting.
