MAX485EESA

Drivers, Receivers, Transceivers Overview

The MAX485EESA is a low-power transceiver designed for RS-485 and RS-422 communications. It features one driver and one receiver in an 8-SOIC surface-mount package. The device operates at data rates up to 2.5 Mb/s with a supply voltage of 5 V. It supports half-duplex communication and includes 15 kV ESD protection on all pins. The unit draws 500 uA in shutdown mode. Operating temperatures range from -40°C to +85°C. Driver output currents range from 35 mA to 250 mA, with output voltages between -8 V and 12.5 V.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and temperature grade. Confirm RoHS compliance status as indicated by the plus sign in the part number. Check current availability through authorized distributors, as stock levels fluctuate. Ensure the SOIC-8 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing RS-485 or RS-422 interfaces requiring high ESD immunity and low power consumption. The 2.5 Mb/s data rate suits most industrial applications. Verify that the 5 V supply voltage aligns with the system power rails. Consider the 8-SOIC package constraints for thermal management and board space. Compare against similar MAX485 variants if different packaging or extended temperature ranges are required.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX485E family of low-power transceivers. It shares functional similarities with the MAX481E, MAX483E, MAX487E, MAX489E, MAX490E, and MAX491E. These parts differ primarily in driver/receiver configurations and termination resistors. The MAX485 variant specifically provides one driver and one receiver for half-duplex operation.

Drivers, Receivers, Transceivers Replacement Considerations

MAX485EESA+T serves as the tape-and-reel alternative for automated assembly. Cross-reference with MAX485ECSA+ for identical electrical performance in the same package. Verify pinout compatibility when substituting with other MAX485 series members.
