MAX1487EESA

Drivers, Receivers, Transceivers Overview

The MAX1487EESA is a low-power, half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates one driver and one receiver in an 8-pin SOIC package. The device supports data rates up to 2.5 Mbps with a supply voltage range of 4.75V to 5.25V. It features ±15kV ESD protection on all pins, slew-rate-limited drivers for reduced electromagnetic interference, and fault-protected receivers that ensure a high logic output during open-circuit conditions. Operating temperatures range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±15kV electrostatic discharge (ESD) protection on all bus pins for harsh environment operation.
• Slew-rate-limited drivers minimize electromagnetic interference (EMI) and reduce signal reflections caused by improper cable termination.
• Fault-protected receiver inputs guarantee a high logic output state when the differential input is open or disconnected.
• Low quiescent current consumption reduces power usage during idle or shutdown states.

Drivers, Receivers, Transceivers Applications

• Multi-point communication networks using RS-485 standards.
• Industrial automation systems requiring robust noise immunity.
• Building automation and control network interfaces.
• Data acquisition systems with long-distance transmission requirements.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official datasheets to confirm temperature grade and packaging type. The base part number indicates the standard industrial grade variant. Confirm RoHS compliance status as manufacturing processes may vary by production batch. Ensure the ordering code matches the required tape-and-reel or tube configuration for your assembly line.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed data transfer up to 2.5 Mbps with significant ESD exposure risks. The slew-rate limitation makes it suitable for noisy environments where signal integrity is critical. Compare with MAX487 if lower data rates are sufficient but similar EMI performance is needed. Ensure the system operates within the specified 4.75V to 5.25V supply range.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX48x/MAX148x family of low-power RS-485/RS-422 transceivers. It shares functional similarities with the MAX487 but offers higher data rate capabilities. The family is designed for balanced digital multipoint communication systems, providing reliable data transmission over twisted-pair cables in electrically noisy industrial settings.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX487EESA is a compatible alternative offering similar functionality with a maximum data rate of 250 kbps. Verify pin compatibility and electrical specifications before substitution. Other variants in the MAX48x series may require level shifting or different termination strategies due to varying slew rates and drive strengths.
