MAX3062EEKA#TG16

Overview

The MAX3062EEKA#TG16 is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates one driver and one receiver within an 8-pin SOT-23 package. The device supports data rates up to 20Mbps with a typical supply current of 910µA at no load. It operates on a single +5V power supply (±5%) across a temperature range of -40°C to +85°C. Key electrical specifications include ±15kV ESD protection via the Human Body Model, a shutdown mode current of 1nA, and a 1/8-unit-load receiver input impedance allowing up to 256 devices on the bus.

Feature Summary

• Fail-safe circuitry guarantees a logic-high receiver output when inputs are open or shorted.
• Hot-swap capability prevents data glitches during board insertion into powered backplanes.
• Non-slew-rate-limited driver design enables high-speed transmission up to 20Mbps.

Applications

• RS-422/RS-485 Communications
• Level Translators
• Transceivers for EMI-Sensitive Applications
• Industrial-Control Local-Area Networks

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required tape-and-reel packaging format. Check for RoHS compliance status as indicated in official documentation. Ensure the part number corresponds to the exact revision and pin configuration required for the target application.

Selection Notes

Select this component for applications requiring high-speed data transmission without slew-rate limiting constraints. It is suitable for systems needing robust fail-safe behavior and hot-swap functionality. Consider the compact SOT-23 package for space-constrained designs. Verify that the 20Mbps rate aligns with system timing requirements compared to slew-rate-limited alternatives.

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, the MAX3062E variant specifically omits this limitation to achieve higher throughput. All members share common features like fail-safe operation and ESD protection.

FAQ

What is the receiver input impedance of the MAX3062E?

The receiver input impedance is 1/8-unit-load (96 kΩ), which allows up to 256 transceivers to be connected on a single communication line.

How does the fail-safe feature operate?

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

What is the purpose of the hot-swap capability?

Hot-swap circuitry eliminates data glitches and prevents disturbances on the differential signal lines when a circuit board is plugged into a hot backplane.
