Product details

Rated for 250kbps data rate, it operates from a 3V to 5.5V supply, covering both 3.3V and 5V logic rails without a separate level translator.

At 250kbps it handles standard UART rates with margin, but falls short of the 1Mbps class.

Package and mounting — board-fit note

Housed in a 28-SSOP (0.209", 5.30mm width) surface-mount package. The supplier device package is also 28-SSOP, so no footprint mismatch between the order code and the actual component.

Frequently asked questions

Does MAX3238EAI+ work with a 3.3V supply?

Yes, the supply range is 3V to 5.5V, so it operates directly on a 3.3V rail without a separate regulator.

What is the data rate of MAX3238EAI+?

The data rate is 250kbps, which covers standard UART rates like 115.2kbps with margin but is below the 1Mbps class.
