Frequently Asked Questions
What is the supply voltage range of the MAX3221EIPWR?
The MAX3221EIPWR operates from a supply voltage of 3V to 5.5V, making it compatible with both 3.3V and 5V logic systems without level-shifting circuitry. This wide range is ideal for mixed-voltage board designs.
What ESD protection does the MAX3221EIPWR provide?
The MAX3221EIPWR provides ±15kV ESD protection (Human Body Model) on all RS-232 transmitter outputs and receiver inputs, significantly reducing the risk of damage from electrostatic discharge during cable hot-plugging or in industrial environments.
What is the maximum data rate supported by the MAX3221EIPWR?
The MAX3221EIPWR supports a maximum data rate of 250kbps, which is well above the standard RS-232 requirement of 115.2kbps, making it suitable for high-speed serial communication in embedded and industrial applications.
What package does the MAX3221EIPWR come in and what are its dimensions?
The MAX3221EIPWR comes in a TSSOP-16 surface-mount package, which offers a compact footprint suitable for space-constrained PCB designs. The 'W' suffix denotes the wide TSSOP body, and it is available on tape-and-reel for automated assembly.
Can the MAX3221EIPWR replace the MAX3232 or SP3221 in existing designs?
The MAX3221EIPWR is pin-compatible with many industry-standard RS-232 transceivers including the SP3221E and similar single-channel devices. However, always verify pinout, supply voltage, and capacitor requirements against your specific layout before substituting in an existing design.
