MAX1487EESA+G104

Drivers, Receivers, Transceivers Overview

The MAX1487EESA+G104 is a low-power, half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features one driver and one receiver housed in an 8-pin SOIC package. The device supports data rates up to 2.5Mbps with a supply voltage range of 4.75V to 5.25V. Driver outputs and receiver inputs are protected against ±15kV electrostatic discharge shocks without latchup. The receiver input impedance is 48kΩ (1/4-unit-load), allowing up to 128 transceivers on the bus. Operating temperature ranges from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±15kV ESD protection on all pins without latchup for harsh environments
• Features quarter-unit-load receiver input impedance enabling high node count networks
• Includes thermal shutdown and short-circuit current limiting for driver protection

Drivers, Receivers, Transceivers Applications

• Low-Power RS-485 Transceivers
• Industrial-Control Local Area Networks
• Level Translators

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific G104 suffix against the manufacturer's official documentation to confirm any variations in packaging or material composition compared to standard variants. Ensure compatibility with existing board layouts and soldering profiles before finalizing procurement decisions.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed transmission up to 2.5Mbps where standard slew-rate limitations are unnecessary. The 1/4-unit-load receiver characteristic makes it suitable for multi-drop bus configurations requiring more than 32 nodes. Verify that the system operates within the specified 5V supply tolerance.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX481E/MAX483E/MAX485E/MAX487E–MAX491E/MAX1487E family of low-power transceivers designed for RS-485 and RS-422 communications. Unlike slew-rate-limited versions in the same series, this model supports higher data rates but may generate more electromagnetic interference.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1487EESA+ is a direct functional replacement for the MAX1487EESA+G104, sharing identical electrical characteristics and pinout. Other compatible parts include the MAX485E and MAX487E, though differences in data rate and receiver load must be evaluated.
