MAX3083ECPD+

Overview

The MAX3083ECPD+ is a full-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and supports data rates up to 500kbps with enhanced slew-rate limiting. The device features ±15kV ESD protection on all I/O pins, fail-safe circuitry ensuring a logic-high receiver output when inputs are open or shorted, and low-power shutdown mode. It utilizes a 14-pin Plastic DIP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Enhanced slew-rate limiting for error-free transmission at speeds up to 500kbps
• Fail-safe receiver guarantees a logic-high output when inputs are open or shorted
• Robust ±15kV electrostatic discharge (ESD) protection on RS-485 I/O pins
• Low-current shutdown mode reduces power consumption during idle periods

Applications

• RS-422 and RS-485 communication networks
• Industrial control local area networks
• Level translation in EMI-sensitive applications

Procurement Notes

Verify the specific suffix 'CPD+' against official manufacturer documentation to confirm the exact package type and temperature grade. Ensure compatibility with existing PCB footprints for the 14-pin Plastic DIP configuration. Cross-reference the component revision with current datasheets to validate electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component for full-duplex applications requiring reliable performance up to 500kbps. The integrated fail-safe feature ensures system stability during bus faults. Verify that the required data rate does not exceed the 500kbps limit imposed by the enhanced slew-rate limiting configuration inherent to the MAX3083E series.

Part Context

This part belongs to the MAX3080E–MAX3089E family of high-speed transceivers designed for RS-485/RS-422 standards. The MAX3083E specifically provides full-duplex operation with fixed slew-rate limiting optimized for 500kbps transmission speeds, distinguishing it from higher-speed variants like the MAX3086E or selectable-speed models like the MAX3089E.

Replacement Considerations

The MAX3080E and MAX3086E are pin-compatible alternatives within the same family. The MAX3080E offers reduced slew rates suitable for 115kbps applications, while the MAX3086E supports un-limited slew rates for 10Mbps communications. Verify functional requirements match the specific speed capabilities of the substitute.
