Product details

The MAX3232EIPWR: This is a standard RS-232 transceiver in a 16-TSSOP package, with two drivers and two receivers, full-duplex operation, and a supply range spanning 3V to 5.5V. It is ROHS3 compliant.

Supply voltage — one part for 3.3V and 5V rails

Rated for 3V to 5.5V, this transceiver operates directly from either a 3.3V or 5V supply rail without needing an external regulator or level translator. That simplifies the power tree and saves board space in mixed-voltage designs. The 250kbps data rate covers the common RS-232 band for terminal interfaces, industrial controllers, and point-of-sale equipment.

Receiver hysteresis of 300 mV provides noise immunity on longer cable runs typical in those environments.

16-TSSOP footprint and surface-mount assembly

The TSSOP body is common across the MAX3232 family, so a single PCB footprint serves multiple speed and ESD grades if the BOM needs to flex.

Frequently asked questions

Is MAX3232EIPWR compatible with both 3.3V and 5V systems?

Yes. The supply range of 3V to 5.5V covers both standard logic rails, so the same part works in a 3.3V or 5V UART interface without additional level shifting.

What is the difference between MAX3232EIPWR and MAX3232EIPW?

The MAX3232EIPWR is the tape-and-reel packaged variant, while the MAX3232EIPW is typically supplied in tubes or trays. The die, electrical specs, and package (16-TSSOP) are identical. For high-volume pick-and-place, the 'R' suffix is the reeled version.

Does MAX3232EIPWR require external capacitors?

Yes, like all MAX3232-family devices, it requires four external charge-pump capacitors (typically 0.1 µF to 1 µF) to generate the RS-232 voltage levels. The exact values are specified in the datasheet layout guidelines.
