Frequently Asked Questions
What serial communication standard does the MAX3221EIPWRE4 support?
The MAX3221EIPWRE4 is compliant with EIA-232-F, TIA-232-F, and ITU V.28 serial communication standards. This makes it fully compatible with standard RS-232 serial ports found on PCs, industrial PLCs, test equipment, and a wide range of legacy embedded systems requiring full-duplex single-channel serial communication.
Can the MAX3221EIPWRE4 operate from a 3.3V supply?
Yes, the MAX3221EIPWRE4 operates from both 3V (3.3V) and 5V supplies. This dual supply compatibility allows it to interface RS-232 logic levels from modern low-voltage 3.3V microcontrollers without additional voltage regulation or level-shifting components, simplifying board design and reducing component count in compact embedded systems.
What package is the MAX3221EIPWRE4 available in?
The MAX3221EIPWRE4 is housed in a 16-pin Thin Shrink Small Outline Package (TSSOP-16), with JESD-30 code R-PDSO-G16. This compact surface-mount package occupies less PCB area than traditional SOIC packages, making it suitable for high-density circuit boards in handheld instruments, embedded computing modules, and space-constrained industrial designs.
What type of input does the MAX3221EIPWRE4 receiver use?
The MAX3221EIPWRE4 uses Schmitt trigger inputs for its receiver section. Schmitt trigger hysteresis provides noise immunity by preventing false triggering from slow-rising or noisy RS-232 signal edges. This is especially beneficial in long cable installations or electrically noisy industrial environments where signal integrity can be compromised by cable capacitance and EMI.
