What are the key features of MAX3223CDBE4?
- Operates from 3 V to 5.5 V supply (also 5 V compatible) for flexible integration with 3.3 V and 5 V systems
- Schmitt-trigger receiver inputs for enhanced noise immunity in electrically noisy RS-232 environments
- Compliant with EIA-232-F, TIA-232-F, and V.28 standards ensuring interoperability with RS-232 equipment
- Integrated charge-pump capacitors support with external caps enabling full RS-232 voltage swing from low-voltage supply
What is MAX3223CDBE4 used for?
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.
