Product details

The Maxim MAX3221ECAE+ is a single RS-232 transceiver in a 16-SSOP package.

It is ROHS3 compliant. If you need a second source or a pin-compatible alternate, the MAX3221ECAE (without the + suffix) is the same die in the same package — the + just marks lead-free finish, so it is a drop-in swap for existing BOMs.

Frequently asked questions

Is MAX3221ECAE+ a direct replacement for MAX3221ECAE?

Yes. The MAX3221ECAE+ is the lead-free (ROHS3) version of the MAX3221ECAE. Electrical specs and pinout are identical — it is a drop-in replacement for existing BOMs.

What are the alternatives to MAX3221ECAE+?

The closest pin-compatible alternative is the MAX3221ECAE (non-plus suffix), which is the same part with tin-lead finish. For a different package, the MAX3221ECUE+ comes in a 16-TSSOP. Both share the same RS-232 core and supply range.
