MAX13081ECSA+

Drivers, Receivers, Transceivers Overview

The MAX13081ECSA+ is a +5.0V, full-duplex 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 250kbps with enhanced slew-rate limiting. The device provides ±15kV ESD protection on I/O pins and incorporates true fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. Operating temperature ranges vary by suffix, typically spanning from -40°C to +85°C for the 'EE' variant.

Drivers, Receivers, Transceivers Feature Summary

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

Drivers, Receivers, Transceivers Applications

• Utility meters
• Industrial control systems
• Telecommunications equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific temperature grade suffix against project requirements, as the base model number covers multiple thermal variants. Confirm the package type matches the PCB footprint, as this part is available in both PDIP and SO configurations. Ensure the ordering suffix corresponds to the desired lead-free and RoHS compliance status before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select the MAX13081ECSA+ for applications requiring full-duplex communication at speeds up to 250kbps. This specific model includes reduced slew-rate drivers suitable for minimizing EMI in electrically noisy environments. Verify that the system does not require half-duplex operation, as other family members like the MAX13082E serve that purpose instead.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX13080E–MAX13089E family of high-speed RS-485 transceivers manufactured by Analog Devices/Maxim Integrated. The family shares common features such as +5.0V operation, fail-safe receivers, and robust ESD protection, while differing in duplex modes and maximum data rates based on the specific numerical suffix.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13081EESA+ serves as a direct pin-compatible alternative in an 8-pin SOIC package. For half-duplex requirements, the MAX13082E series offers similar electrical characteristics but with different control logic. Higher speed options within the same family include the MAX13086E through MAX13088E.
