MAX13085ECSA+T

Drivers, Receivers, Transceivers Overview

The MAX13085ECSA+T is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates one driver and one receiver, operating from a single +5.0V supply with a voltage range of 4.5V to 5.5V. The device supports data rates up to 500kbps and features ±15kV ESD protection on I/O pins. It includes fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. Hot-swap capability prevents false transitions during power-up or insertion. The typical supply current is 1.8mA, and it operates within an extended temperature range of -40°C to +85°C in an 8-pin SO package.

Drivers, Receivers, Transceivers Feature Summary

• Hot-swap input structures on DE and RE pins eliminate false bus transitions during hot insertion or power-up sequences.
• True fail-safe receiver design ensures a logic-high output state when receiver inputs are left open or shorted.
• Enhanced slew-rate limiting minimizes electromagnetic interference (EMI) and reduces signal reflections on improperly terminated cables.

Drivers, Receivers, Transceivers Applications

• Utility Meters
• Industrial Control Systems
• Telecommunications Equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature range availability against official documentation. Confirm the '+T' designation corresponds to tape-and-reel packaging requirements for automated assembly processes. Ensure the component matches the exact manufacturer part number to avoid compatibility issues with existing designs.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring half-duplex communication with moderate speed requirements up to 500kbps. The integrated hot-swap feature makes it suitable for systems requiring board insertion while powered. Verify that the 8-pin SO package dimensions fit the available PCB footprint constraints before finalizing the design.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX13080E–MAX13089E family of +5.0V, ±15kV ESD-protected RS-485 transceivers. The family shares common architectural features such as fail-safe receivers and low-power shutdown modes. Specific variants differ primarily in duplex mode, maximum data rate capabilities, and pin-selectable features like slew rate control.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional substitutes within the same series include the MAX13082ECSA+T and MAX13088ECSA+T, which also provide half-duplex operation. When replacing, verify that the thermal dissipation characteristics and package outline dimensions remain compatible with the original layout.
