Applications
The MAX3223CDBE4 is used in embedded systems, industrial controllers, and communication equipment requiring a reliable RS-232 serial interface between a 3.3 V microcontroller and legacy RS-232 peripherals such as modems, barcode scanners, and GPS modules. Its wide supply range makes it suitable for battery-operated designs and mixed-voltage boards where 3.3 V logic must interface with 5 V RS-232 levels. Engineers also deploy it in test instruments and medical devices needing compliant serial data communication with PC or host interfaces.

Frequently Asked Questions
What serial communication standard does the MAX3223CDBE4 support?
The MAX3223CDBE4 supports EIA-232-F, TIA-232-F, and V.28 serial communication standards, which collectively define the RS-232 interface used widely in industrial serial communication, modem connections, and PC peripheral interfaces.
What supply voltage range does the MAX3223CDBE4 operate from?
The MAX3223CDBE4 operates from a supply voltage of 3 V to 5.5 V and can also operate with a 5 V supply. This dual-voltage compatibility makes it easy to use in both legacy 5 V systems and modern 3.3 V microcontroller-based designs.
How many drivers and receivers are in the MAX3223CDBE4?
The MAX3223CDBE4 contains two RS-232 line drivers and two receivers (2Tx/2Rx multichannel configuration), providing a complete two-channel full-duplex RS-232 interface in a single 20-pin SOIC package.
What type of inputs do the receivers in the MAX3223CDBE4 use?
The receivers use Schmitt-trigger inputs with a very low high-level input current maximum of 1 µA, providing hysteresis that improves noise rejection and ensures clean digital transitions even on slow or noisy RS-232 signal lines.
What package does the MAX3223CDBE4 come in?
The MAX3223CDBE4 is housed in a 20-pin SOIC package (JESD-30 code R-PDSO-G20) and is available in a bulk tape-and-reel format (E4 suffix). The package is RoHS compliant (JESD-609 code e4) and suitable for standard SMT assembly.
