MAX3227EEAE+

Overview

The MAX3227EEAE+ is a single-driver, single-receiver full-duplex RS-232 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a +3.0V to +5.5V supply and supports data rates up to 1Mbps. The device features AutoShutdown Plus technology, reducing supply current to 1μA when inputs are inactive for over 30 seconds. It includes ±15kV ESD protection on all I/O pins and provides a READY output signal indicating charge pump regulation status.

Feature Summary

• AutoShutdown Plus functionality automatically reduces power consumption during periods of inactivity or cable disconnection.
• Integrated dual charge pumps generate internal voltage rails from a single low-voltage supply using minimal external capacitors.
• High electrostatic discharge tolerance protects transmitter outputs and receiver inputs against severe static events.

Applications

• Notebook, subnotebook, and palmtop computers
• Cellular phones and battery-powered equipment
• Hand-held devices and peripherals such as printers

Procurement Notes

Verify the specific suffix EEAE corresponds to the SSOP-16 package and industrial temperature range (-40°C to +85°C) required for your design. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when a single-channel RS-232 interface with high-speed 1Mbps capability is needed. Ensure the application requires the specific 16-pin SSOP footprint and that the system can accommodate the four small capacitors necessary for the internal charge pump operation.

Part Context

This part belongs to the MAX3224E/MAX3225E/MAX3226E/MAX3227E family of RS-232 transceivers. It shares core architectural features like AutoShutdown Plus and ESD protection with siblings such as the MAX3226E, differing primarily in guaranteed data rate specifications and driver/receiver counts.

Replacement Considerations

The MAX3227EEUE+ serves as a direct pin-compatible alternative utilizing a TSSOP-16 package instead of SSOP. Other family members like the MAX3226E offer similar functionality but are limited to lower data rates.
