MAX3080ECSD+T

Overview

The MAX3080ECSD+T is a full-duplex RS-485/RS-422 transceiver featuring one driver and one receiver. It operates within a supply voltage range of 4.75V to 5.25V, drawing a typical quiescent current of 375µA. The device supports data transmission rates up to 115kbps with slew-rate limiting enabled. It provides ±15kV ESD protection on all I/O pins and incorporates fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. The component is housed in a 14-pin SOIC package and is rated for an operating temperature range of 0°C to +70°C.

Feature Summary

• Fail-safe receiver circuitry ensures a logic-high output state during bus idle conditions or input disconnection.
• Slew-rate limited drivers minimize electromagnetic interference and reduce signal reflections on improperly terminated cables.
• Enhanced electrostatic discharge protection rated at ±15kV via the Human Body Model across all communication pins.

Applications

• RS-422 and RS-485 serial communication networks
• Industrial control local area networks
• Level translation interfaces for microprocessor systems

Procurement Notes

Verify the specific suffix 'CSD' confirms the commercial temperature range (0°C to +70°C) and surface-mount SOIC packaging. Confirm the '+T' designation indicates tape-and-reel delivery format. Ensure compatibility with standard 5V logic levels before integration into existing designs.

Selection Notes

Select this model for applications requiring error-free transmission up to 115kbps where reduced EMI is critical. Choose this part over higher-speed variants if minimizing signal reflections on unterminated lines is a priority. Verify that the commercial temperature range meets the environmental requirements of the target deployment site.

Part Context

This component belongs to the MAX3080E–MAX3089E family of high-speed transceivers designed for RS-485 and RS-422 standards. The family shares pinout compatibility with industry-standard devices like the 75180, facilitating direct replacements in legacy designs while offering enhanced ESD protection and configurable operational modes.

Replacement Considerations

Pin-compatible with the 75180. Verify electrical parameters against the original component datasheet to ensure adequate noise margins and drive strength for the specific bus topology.
