MAX3490ECPA

Drivers, Receivers, Transceivers Overview

The MAX3490ECPA is a true RS-485 and RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.3V supply without requiring a charge pump, ensuring interoperability with +5V logic. The device features a guaranteed data rate of 12Mbps and includes slew-rate limiting for errorless data transmission. It provides ±15kV ESD protection on RS-485 I/O pins according to the Human Body Model and ±8kV contact discharge per IEC 1000-4-2. The component supports a common-mode input voltage range of -7V to +12V and incorporates current-limiting and thermal shutdown for driver overload protection.

Drivers, Receivers, Transceivers Feature Summary

• ESD protection rated at ±15kV (Human Body Model) and ±8kV (IEC 1000-4-2 Contact Discharge) for robust signal integrity
• Slew-rate limited output drivers designed to minimize electromagnetic interference and ensure errorless data transmission
• Integrated current-limiting and thermal shutdown mechanisms to protect against driver overload conditions

Drivers, Receivers, Transceivers Applications

• Industrial communication networks utilizing RS-485 or RS-422 protocols
• Embedded systems requiring low-power differential signaling over long distances
• Control systems operating in environments with high electrostatic discharge risks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ECPA' against official datasheets to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for the CP package variant. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 12Mbps data rate is required alongside strict ESD protection standards. It is suitable for designs needing slew-rate limiting to reduce noise. Verify that the system power supply aligns with the +3.3V requirement and that logic levels are compatible with +5V interoperability.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX3483E family of transceivers, which includes variants like MAX3483E, MAX3485E, and MAX3491E. These devices share similar architectural features but differ in duplex mode and specific performance characteristics such as data rate and shutdown capabilities within the same product line.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other members of the MAX3483E family, such as the MAX3485E or MAX3491E, provided pinout and functional requirements match. Cross-reference with ADM3488 series components for equivalent performance in RS-485/RS-422 applications.
