MAX13085ECSA+

Drivers, Receivers, Transceivers Overview

The MAX13085ECSA+ is a +5.0V RS-485 transceiver featuring one driver and one receiver in an 8-pin SO package. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 500kbps with slew-rate-limited drivers. The device provides ±15kV ESD protection on I/O pins, fail-safe circuitry ensuring a logic-high output when inputs are open or shorted, and hot-swap capability on the DE and RE pins. It draws 1.2mA typical supply current and functions over an extended temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Hot-swap input structures on DE and RE pins prevent false transitions during power-up or bus insertion.
• True fail-safe receiver guarantees a logic-high output when receiver inputs are open or shorted while maintaining EIA/TIA-485 compatibility.
• Enhanced slew-rate limiting minimizes electromagnetic interference (EMI) and reduces reflections from improperly terminated cables.

Drivers, Receivers, Transceivers Applications

• Utility Meters
• Industrial Control Systems
• Telecommunications Equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ECSA+' against official documentation to confirm the 8-pin SOIC package and commercial/extended temperature grade. Ensure the ordering code matches the exact lead-free/RoHS-compliant variant required for your assembly process. Cross-reference the manufacturer's latest datasheet revision to confirm pinout and electrical characteristics remain unchanged.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust RS-485 communication with hot-swap support. The MAX13085E specifically offers a 500kbps data rate with slew-rate limiting, distinguishing it from the 250kbps MAX13082E and high-speed MAX13086E. Verify that the half-duplex configuration meets system requirements, as full-duplex variants like the MAX13084E exist within the same family.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX13080E–MAX13089E family of +5.0V RS-485 transceivers manufactured by Analog Devices Inc./Maxim Integrated. The family shares common features such as ±15kV ESD protection and fail-safe operation but varies in duplex mode and maximum data rates. The MAX13085E is positioned as a half-duplex solution with intermediate speed capabilities.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13082E is a compatible alternative offering similar functionality but limited to 250kbps data rates. For higher speed requirements, the MAX13086E provides 16Mbps transmission without slew-rate limiting. Both alternatives maintain the same +5.0V operation and ESD protection specifications.
