MAX3162EEAI+T

Overview

The MAX3162EEAI+T is a dual RS-422/RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +3.0V to +5.5V and supports data rates up to 10 Mb/s. The device features 15 kV ESD protection on the bus pins and includes two drivers and two receivers. It functions in an extended temperature range from -40°C to +85°C and is housed in a 28-pin SSOP package.

Feature Summary

• Integrated charge pump circuit enables single-supply operation without requiring negative voltage rails.
• Transceivers provide fault protection against wiring errors and short circuits on the bus lines.
• True fail-safe receiver design prevents false triggering when inputs are open or shorted.

Applications

• Industrial communication networks utilizing RS-485 multi-drop topologies
• Building automation systems requiring robust serial data transmission
• Process control equipment operating in electrically noisy environments

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component for applications requiring high-speed differential signaling with integrated power management. Ensure the system design accommodates the internal charge pump requirements and that the SSOP-28 footprint matches the PCB layout constraints.

Part Context

This part belongs to the MAX3162E series, which offers flexible interface options for both RS-232 and RS-485/RS-422 protocols. The EEAI+ designation specifies the industrial temperature grade and lead-free construction compliant with environmental standards.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult manufacturer cross-reference guides for pin-compatible alternatives if necessary.
