MAX3061EEKA+T

Overview

The MAX3061EEKA+T is a half-duplex RS-485/RS-422 transceiver in an 8-pin SOT23 package. It supports data rates up to 500kbps with slew-rate-limited drivers. The device operates on a single +5V supply (4.75V to 5.25V) and draws 910µA typical supply current. It features ±15kV Human Body Model ESD protection, fail-safe circuitry guaranteeing a logic-high receiver output when inputs are open or shorted, and hot-swap capability for telecom applications. The receiver input impedance is 1/8-unit-load, allowing up to 256 transceivers on the bus.

Feature Summary

• Slew-rate limiting minimizes electromagnetic interference and reduces signal reflections
• Fail-safe receiver guarantees a logic-high output during idle or fault conditions
• Hot-swap circuitry prevents data glitches during board insertion into powered backplanes
• High input impedance allows connection of up to 256 devices on a single bus

Applications

• RS-422 and RS-485 communication networks
• Level translation interfaces
• EMI-sensitive industrial control local-area networks
• Telecom equipment requiring hot-swappable modules

Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required tape-and-reel packaging format. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before integration into production systems.

Selection Notes

Select this component for designs requiring moderate-speed differential signaling with enhanced noise immunity. The integrated slew-rate limiting makes it suitable for long cable runs where signal integrity is critical. Verify that the system power supply remains within the specified +5V tolerance range to ensure reliable operation across the full temperature spectrum.

Part Context

This device belongs to the MAX306xE family, which includes the MAX3060E and MAX3062E variants. While sharing the same package and basic interface standards, the MAX3060E offers lower speeds with stronger slew-rate limiting, and the MAX3062E provides higher speeds without slew-rate limitation. All three share identical pinouts and fail-safe characteristics.

Replacement Considerations

The MAX3060EEKA+T and MAX3062EEKA+T are direct pin-compatible alternatives within the same series. Designers should verify that the specific data rate requirements align with the replacement's capabilities, as the MAX3060E is limited to 115kbps and the MAX3062E supports up to 20Mbps.
