What are the key features of MAX3223CDBRE4?
- Wide 3 V to 5.5 V supply range supports both 3.3 V and 5 V logic systems without level-shifting
- Integrated charge-pump capacitors reduce external BOM to four small capacitors, simplifying PCB layout
- Schmitt-trigger inputs provide enhanced noise immunity on RS-232 receive lines in noisy industrial environments
- EIA-232-F / TIA-232-F / V.28 compliant with two drivers and two receivers in a compact 20-pin SSOP
What is MAX3223CDBRE4 used for?
The MAX3223CDBRE4 is ideal for RS-232 serial communication links in industrial equipment, handheld terminals, and embedded microcontroller systems that operate from a 3.3 V supply. Its ability to also run from 5 V makes it a drop-in upgrade in legacy designs. The integrated charge-pump eliminates the need for an external ±12 V supply, simplifying power architecture in space-constrained portable and battery-powered devices.

Frequently Asked Questions
What supply voltage range does the MAX3223CDBRE4 support?
The MAX3223CDBRE4 operates from 3 V to 5.5 V, making it compatible with both 3.3 V and 5 V system supply rails without requiring additional level translation circuitry, which simplifies mixed-voltage board designs.
Does the MAX3223CDBRE4 require external capacitors for the charge pump?
Yes, the charge-pump oscillator requires four external capacitors, typically 0.1 µF each, to generate the ±5.5 V RS-232 output swing internally. This eliminates the need for a separate ±12 V power supply, reducing overall system cost and complexity.
How many drivers and receivers does the MAX3223CDBRE4 integrate?
The MAX3223CDBRE4 integrates two RS-232 line drivers and two RS-232 line receivers, making it suitable for full RS-232 port implementations (TX, RX, RTS, CTS) in a single 20-pin SSOP package.
What interface standards is the MAX3223CDBRE4 compliant with?
The device is compliant with EIA-232-F, TIA-232-F, and ITU-T V.28 standards, ensuring interoperability with any RS-232 host, terminal, or modem that adheres to these widely adopted serial communication specifications.
What is the package type and does it come on tape and reel?
The MAX3223CDBRE4 is housed in a 20-pin SSOP (PDSO-G20) package. The E4 suffix indicates the part is RoHS compliant and lead-free, and the DBR suffix designates tape-and-reel packaging suitable for automated surface-mount assembly.
