MAX3224EEPP+

Overview

The MAX3224EEPP+ is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 20-pin Plastic DIP package. It operates on a single +3.0V to +5.5V supply and features AutoShutdown Plus technology, achieving a typical supply current of 1μA during shutdown. The device guarantees a data rate of 250kbps with full duplex communication. It includes two drivers and two receivers, providing ±15kV ESD protection via the Human Body Model. The operating temperature range extends from -40°C to +85°C.

Feature Summary

• AutoShutdown Plus functionality automatically reduces power consumption when the interface is idle or disconnected.
• Integrated dual charge pump generates internal voltage levels without requiring external transformers.
• Robust electrostatic discharge protection ensures reliability in high-interference environments.
• Logic-level READY output indicates when the internal charge pumps are regulating and ready for transmission.

Applications

• Notebook, Subnotebook, and Palmtop Computers
• Cellular Phones and Battery-Powered Equipment
• Hand-Held Equipment and Peripherals
• Printers and Automotive Systems

Procurement Notes

Verify the specific suffix EEPP corresponds to the 20-pin Plastic DIP package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status as indicated by the plus sign. Ensure the source document matches the official Analog Devices datasheet for accurate pinout and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component for applications requiring low-power standby modes in battery-operated devices. The 250kbps data rate suits standard serial communications where higher speeds are unnecessary. Consider the Plastic DIP package only if through-hole mounting is required; otherwise, SSOP or TQFN variants offer smaller footprints. Verify that the 2-driver/2-receiver configuration meets the system's I/O requirements.

Part Context

This part belongs to the MAX3224E/MAX3225E/MAX3226E/MAX3227E/MAX3244E/MAX3245E family of RS-232 transceivers. These devices share common features such as AutoShutdown Plus and ±15kV ESD protection but differ in driver/receiver counts and maximum data rates. The MAX3224E specifically provides a 2/2 configuration with a 250kbps guarantee.
