MAX13085EESA+T

Drivers, Receivers, Transceivers Overview

The MAX13085EESA+T is a half-duplex RS-485 transceiver from the MAX13080E family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5.0V supply (4.5V to 5.5V) and supports data rates up to 500kbps with slew-rate-limited drivers. The device features ±15kV ESD protection on I/O pins, fail-safe circuitry ensuring a logic-high receiver output when inputs are open or shorted, and hot-swap capability on DE and RE inputs. It includes one driver and one receiver in an 8-pin SO package, operating within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Hot-swap input structures on DE and RE prevent false transitions during power-up or bus insertion
• Fail-safe receiver guarantees a logic-high output when inputs are open or shorted
• Slew-rate limiting minimizes EMI and reflections for error-free transmission at specified speeds

Drivers, Receivers, Transceivers Applications

• Utility Meters
• Industrial Control Systems
• Telecommunications Equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube, as standard datasheets often list tube packaging for the base model. Confirm the exact thermal and electrical specifications match the intended application requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust RS-485 communication with hot-swap capabilities. Ensure the system design accommodates the 500kbps maximum data rate and the specific 8-pin SOIC footprint constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13080E–MAX13089E family of +5.0V, ±15kV ESD-protected, fail-safe, hot-swap RS-485 transceivers. The MAX13085 variant specifically provides half-duplex operation with slew-rate-limited drivers optimized for 500kbps transmission speeds.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements within the same family include MAX13084EESA+T (full-duplex) or MAX13082EESA+T (half-duplex, 250kbps). Verify pin compatibility and duplex mode requirements when substituting.
