Both use four external 0.1µF capacitors to generate the required RS-232 signal levels.
Both chips are 2-driver, 2-receiver RS-232 transceivers. They are designed to bridge the gap between low-voltage logic (TTL/CMOS) and the higher voltage requirements of the RS-232 standard. Both operate from 3.0V to 5.5V. sp3232+vs+max3232+exclusive
Generally boasts a higher standard data rate of 235 kbps . If your baud rate is pushing the limits, the SP3232 offers more "headroom" for signal integrity. 2. Power Consumption For battery-powered IoT devices, every microamp counts. Both use four external 0
You need a slightly (up to 235kbps) without moving to a specialized high-speed chip. Both operate from 3
Budget is secondary to and long-term availability. Choose the SP3232 if:
Standard versions usually offer ±15kV ESD protection on the RS-232 I/O pins. Maxim is the industry gold standard for robustness.
