MAX3060EEKA+T

Overview

The MAX3060EEKA+T is a half-duplex RS-485/RS-422 transceiver in an 8-pin SOT23 package. It operates from a +4.75V to +5.25V supply with typical current draw of 910µA. The device features fail-safe circuitry guaranteeing a logic-high receiver output when inputs are open or shorted, and hot-swap capability to prevent data glitches during insertion. The driver is slew-rate limited for error-free transmission up to 115kbps. It supports up to 256 transceivers on the bus due to its 1/8-unit-load input impedance and includes ±15kV Human Body Model ESD protection.

Feature Summary

• Fail-safe receiver guarantees a logic-high output when differential inputs are open, shorted, or disconnected.
• Hot-swap input structure prevents data disturbances and bus errors during board insertion into powered backplanes.
• Slew-rate-limited driver minimizes electromagnetic interference (EMI) and reduces signal reflections on improperly terminated cables.
• High input impedance allows connection of up to 256 transceivers on a single communication bus.

Applications

• RS-422 and RS-485 communications networks
• Industrial-control local-area networks
• Level translators in mixed-voltage systems
• Transceivers for EMI-sensitive applications

Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the operating temperature range meets system requirements. Check for lead-free compliance if required by assembly standards. Confirm that the SOT23-8 package dimensions align with the PCB footprint design constraints.

Selection Notes

Select this component for applications requiring reduced EMI and reliable operation on long or poorly terminated buses. The MAX3060E is suitable where data rates do not exceed 115kbps. Compare against MAX3061E for higher speed limits or MAX3062E for non-slew-limited performance. Verify that the 1/8-unit-load capacity matches the network node count requirements.

Part Context

This part belongs to the MAX3060E/MAX3061E/MAX3062E family of high-speed transceivers designed for RS-485/RS-422 communication. All variants share the same 8-pin SOT23 package and core features like fail-safe and hot-swap capabilities. The primary distinction lies in the maximum data rate and slew-rate limiting configuration.

Replacement Considerations

MAX3061EEKA+T offers similar features with a 500kbps data rate limit. MAX3062EEKA+T provides 20Mbps speed without slew-rate limiting. Other Maxim Integrated RS-485 transceivers may require verification of pinout and electrical parameter compatibility before substitution.
