MAX13081ECSA+T

Drivers, Receivers, Transceivers Overview

The MAX13081ECSA+T is a full-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5.0V supply with a voltage range of 4.5V to 5.5V and draws 1.2mA typical supply current. The device features one driver and one receiver, supporting data rates up to 250kbps with enhanced slew-rate limiting. It provides ±15kV ESD protection on I/O pins and includes true fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. Packaged in an 8-pin SOIC (SOP-8) format, it is designed for robust communication in industrial environments.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced slew-rate limiting minimizes electromagnetic interference and reduces signal reflections caused by improperly terminated cables.
• True fail-safe receiver circuitry ensures a logic-high output state when the differential receiver inputs are left open or shorted.
• Integrated hot-swap input structures on DE and RE pins prevent false transitions and erroneous data transfer during bus insertion.

Drivers, Receivers, Transceivers Applications

• Utility Meters
• Industrial Control Systems
• Telecommunications Equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature operation and 'SA' denotes the SOIC package. Confirm '+T' signifies tape-and-reel packaging if required for automated assembly. Cross-reference the manufacturer part number against official Analog Devices documentation to ensure authenticity and correct revision status before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex RS-485 communication at speeds up to 250kbps. Ensure the design environment accommodates the specified operating temperature range associated with the 'C' suffix. Verify that the system power supply remains within the 4.5V to 5.5V range to maintain optimal electrical performance and compliance with interface standards.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX13080E–MAX13089E family of +5.0V, ±15kV ESD-protected RS-485 transceivers. While sharing core features like fail-safe operation and hot-swap capability, the MAX13081E specifically supports full-duplex communication. Other family members may offer half-duplex modes, higher data rates, or pin-selectable slew rates, making the MAX13081E suitable for standard full-duplex low-speed applications.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13081EASA+T serves as a direct functional replacement for the MAX13081ECSA+T, differing only in package type (SOIC vs. PDIP). For alternative sourcing, verify compatibility with other MAX1308x series devices, noting that variations exist in duplex mode and maximum data rates across the family.
