MAX3224EETP+

Overview

The MAX3224EETP+ is a dual RS-232 transceiver manufactured by Analog Devices (Maxim Integrated). It operates from a single +3.0V to +5.5V supply and guarantees a data rate of 250kbps. The device features AutoShutdown Plus technology, reducing supply current to 1μA when idle. It includes two drivers and two receivers with full-duplex communication capability. ESD protection is rated at ±15kV for air discharge and ±8kV for contact discharge. The component is housed in a 20-pin TQFN-EP package and supports an industrial operating temperature range of -40°C to +85°C.

Feature Summary

AutoShutdown Plus functionality automatically reduces power consumption during periods of inactivity or cable disconnection.
Integrated dual charge pump generates internal voltage levels using only four small external capacitors.
Enhanced electrostatic discharge protection on all transmitter outputs and receiver inputs.

Applications

Notebook, subnotebook, and palmtop computers
Cellular phones and battery-powered equipment
Automotive systems

Procurement Notes

Verify the specific suffix EE indicates the extended temperature range (-40°C to +85°C) compared to EC variants. Confirm the TQFN-EP package requires soldering the exposed pad to the ground plane for optimal thermal performance. Ensure the ordering part number matches the required pinout and RoHS compliance status indicated by the plus sign.

Selection Notes

Select this model over the MAX3225E if a guaranteed 1Mbps data rate is not required, as the MAX3224E is optimized for 250kbps applications. Consider the MAX3244E if additional receiver channels are needed. Verify that the system design accommodates the 0.1μF external capacitors required for the charge pump operation within the specified voltage range.

Part Context

This component belongs to the MAX3224E/MAX3225E/MAX3226E/MAX3227E/MAX3244E/MAX3245E family of low-power RS-232 transceivers. These devices share common features such as AutoShutdown Plus and high ESD protection but differ in driver/receiver counts and maximum data rates. The MAX3224E specifically provides a dual-driver configuration suitable for standard serial communications.
