MAX3085EEPA

Overview

The MAX3085EEPA+ is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply and supports data rates up to 500kbps with enhanced slew-rate limiting. The device features ±15kV ESD protection, fail-safe receiver circuitry, and low-power shutdown mode. It is housed in an 8-pin PDIP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Enhanced slew-rate limiting for error-free transmission at speeds up to 500kbps
• Fail-safe receiver guarantees logic-high output when inputs are open or shorted
• ±15kV electrostatic discharge (ESD) protection on all I/O pins

Applications

• RS-422/RS-485 communications
• Industrial-control local area networks
• Transceivers for EMI-sensitive applications

Procurement Notes

Verify the exact ordering suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status as required by project specifications. Check current availability and lifecycle status through authorized distributors before finalizing procurement plans.

Selection Notes

Select this component for half-duplex RS-485 applications requiring 500kbps data rates. Ensure the system design accommodates the 8-pin PDIP footprint. Verify that the +5V supply voltage aligns with the target power architecture and that the industrial temperature range meets environmental requirements.

Part Context

This part belongs to the MAX3080E–MAX3089E family of high-speed transceivers. It shares pin compatibility with industry-standard devices like the 75180 but includes additional internal features. The 'E' suffix denotes the extended temperature range, while 'PA+' indicates the specific PDIP packaging and lead-free composition.

Replacement Considerations

Pin-compatible alternatives include the SN65HVD3085 and generic equivalents such as GM3085E or DP3085. Verify electrical parameters and package dimensions before substitution.
