MAX3062EEKA+T

Overview

The MAX3062EEKA+T is a half-duplex RS-485/RS-422 transceiver in an 8-pin SOT-23 package. It supports data rates up to 20Mbps with a typical supply current of 910µA at VCC = +5V. The device features fail-safe circuitry guaranteeing a logic-high receiver output when inputs are open or shorted, and hot-swap capability to prevent bus disturbances during insertion. Driver outputs provide ±15kV ESD protection via the Human Body Model. Operating temperature range is -40°C to +85°C.

Feature Summary

• Fail-safe receiver guarantees a logic-high output when differential inputs are open, shorted, or disconnected from active drivers.
• Hot-swap input structure prevents data glitches on the bus during board insertion into powered backplanes.
• Non-slew-rate-limited driver enables high-speed transmission up to 20Mbps without signal distortion constraints.

Applications

• RS-422/RS-485 communications
• Industrial-control local-area networks
• Level translators

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status and lead-free designation through manufacturer datasheets. Ensure the component matches the required thermal and electrical specifications for the target application environment before procurement.

Selection Notes

Select this component for applications requiring high-speed data transmission up to 20Mbps where slew-rate limiting is not desired. It is suitable for systems needing robust ESD protection and fail-safe operation on RS-485/RS-422 buses. Verify that the 1/8-unit-load receiver impedance allows for the required number of nodes on the network.

Part Context

This part belongs to the MAX3060E/MAX3061E/MAX3062E family of high-speed transceivers. While the MAX3060E and MAX3061E feature slew-rate limiting for lower speeds (115kbps and 500kbps respectively), the MAX3062E variant removes this limitation to support faster data rates up to 20Mbps within the same compact SOT-23 footprint.

FAQ

How does the fail-safe feature function?

The fail-safe circuitry guarantees a logic-high receiver output when the receiver inputs are open, shorted, or connected to a terminated line with all drivers disabled.

What is the purpose of the hot-swap capability?

Hot-swap circuitry eliminates data glitches on the differential signal lines when a circuit board is plugged into a hot backplane by holding enable inputs in a defined state during power-up.

Does the MAX3062E have slew-rate limiting?

No, the MAX3062E driver is not slew-rate limited, which allows it to achieve transmit speeds up to 20Mbps.
