Key Features
- Wide 3 V to 5.5 V supply range with EIA-232-F/TIA-232-F compliant dual driver and dual receiver channels for flexible voltage interfacing
- Schmitt-trigger receiver inputs with 1 µA input leakage current enabling reliable signal detection in noisy serial communication environments
- 16-pin SOIC package with integrated charge-pump voltage doubler, requiring only four small external capacitors for full RS-232 ±5 V swing generation
Applications
The MAX3232EIPWE4 is ideal for microcontroller UART-to-RS-232 level translation in industrial PLCs, embedded computing boards, and test equipment that must communicate with legacy RS-232 serial ports at 3.3 V or 5 V system voltage. Its wide 3 V to 5.5 V supply compatibility and dual-channel architecture allow a single IC to replace both the driver and receiver halves of full-duplex serial links in compact 16-pin SOIC form factor designs.

Frequently Asked Questions
What supply voltage range does the MAX3232EIPWE4 support and how does this compare to standard 5 V RS-232 transceivers?
The MAX3232EIPWE4 operates from 3 V to 5.5 V, making it compatible with both 3.3 V microcontroller systems and legacy 5 V designs. Standard RS-232 transceivers often require a fixed 5 V rail, so the MAX3232E's wide range eliminates level-shifting stages and simplifies integration with modern low-voltage SoCs and FPGAs.
How many driver and receiver channels does the MAX3232EIPWE4 provide for full-duplex RS-232 communication?
The MAX3232EIPWE4 integrates 2 driver outputs and 2 receiver inputs, providing a complete full-duplex RS-232 interface in one 16-pin SOIC package. This dual-channel configuration handles both transmit and receive paths of a standard RS-232 serial port simultaneously, covering EIA-232-F and TIA-232-F interface standards.
What advantage do the Schmitt-trigger inputs on the MAX3232EIPWE4 provide in electrically noisy industrial installations?
The Schmitt-trigger receiver inputs of the MAX3232EIPWE4 add hysteresis to the switching threshold, rejecting input signal noise and slow-rising edges common on long RS-232 cable runs. With maximum input leakage of 1 µA, the receivers remain high-impedance and do not load the cable, maintaining signal integrity over cable lengths up to 15 m at standard baud rates.
What external components are required to complete the charge pump in the MAX3232EIPWE4 design?
The MAX3232EIPWE4 requires only 4 external capacitors (typically 100 nF each) for its internal charge-pump voltage doubler and inverter, which generate the ±5 V RS-232 swing from the 3 V to 5.5 V supply. No external transformer or secondary supply is needed, minimizing BOM to just 4 small ceramic capacitors for the complete level-translation circuit.
