What are the key features of MAX3223EEPP?
- 15 kV ESD protection on RS-232 I/O pins, exceeding the standard ±2 kV requirement for robust field deployment
- AutoShutdown mode reduces supply current to below 1 µA when no RS-232 cable activity is detected
- Wide supply range of 3.0 V to 5.5 V with integrated charge-pump capacitors, eliminating external boost components
- 250 kbps guaranteed data rate with low 300 ns propagation delay for reliable high-speed serial links
- DIP-18 package with through-hole mounting for easy prototyping and legacy industrial equipment maintenance
What is MAX3223EEPP used for?
The MAX3223EEPP is ideal for industrial control panels, barcode scanners, and point-of-sale terminals that use RS-232 serial ports in environments with high electrostatic discharge risk, thanks to its 15 kV protection level. Its AutoShutdown feature extends battery life in portable instruments by cutting quiescent current to under 1 µA when no RS-232 activity is detected on the 3.0 V to 5.5 V supply rail. Legacy test equipment upgrades and embedded microcontroller UART-to-RS-232 bridges also benefit from its integrated charge-pump capacitors, which allow single-supply operation without external boost circuitry.

Frequently Asked Questions
What ESD protection level and data rate does MAX3223EEPP provide on its RS-232 pins?
The MAX3223EEPP guarantees ±15 kV Human Body Model ESD protection on all RS-232 I/O pins, far exceeding the ±2 kV rating of standard transceivers. It supports a data rate of up to 250 kbps with propagation delays below 300 ns, making it reliable for time-sensitive industrial serial protocols such as Modbus RTU at standard baud rates from 9600 bps to 115200 bps.
Which industrial and embedded applications benefit most from deploying MAX3223EEPP in an RS-232 interface design?
Factory automation controllers, barcode scanners, and point-of-sale terminals that operate in high-ESD environments are prime candidates because the 15 kV protection eliminates the need for external TVS diodes on RS-232 connectors. Embedded UART-to-RS-232 bridges in PLCs running from 3.3 V microcontrollers also benefit from the integrated charge pump, which generates ±5.5 V RS-232 levels without a separate power rail, reducing BOM cost by 2 to 3 components.
When would a designer choose MAX3223EEPP over MAX3232 for a new RS-232 port design?
A designer would select MAX3223EEPP when ESD protection beyond ±2 kV and an AutoShutdown power-saving feature are required, since MAX3232 lacks both. The MAX3223EEPP reduces supply current to below 1 µA automatically after 30 ms of RS-232 inactivity, which is critical for battery-powered handheld instruments running from 3.3 V lithium cells. MAX3232 offers 2 drivers and 2 receivers versus MAX3223's 1T/1R ratio, so MAX3232 is preferred when multiple RS-232 channels are needed in a non-ESD-critical application.
How does AutoShutdown mode in MAX3223EEPP extend battery life in portable serial instruments?
AutoShutdown monitors the RS-232 receiver input and after approximately 30 ms of inactivity reduces supply current from 1 mA active to below 1 µA, extending battery runtime by orders of magnitude during idle periods. When RS-232 activity resumes, the device wakes within 100 µs without microcontroller intervention, maintaining transparent serial communication. A handheld instrument running from a 1000 mAh, 3.3 V cell and polling at 5% duty cycle can extend battery life from roughly 42 hours to over 1000 hours using this feature.
