Product details

RS232 transceiver for legacy serial links — 250 kbps, 2/2 driver/receiver, 16-SOIC

The 16-SOIC wide-body footprint (7.50 mm width) is a standard outline shared across the MAX232 family, easing second-sourcing if needed.

The 4.5 V minimum supply means this transceiver runs cleanly from a 5 V ±10% rail without a separate regulator. If your board uses 3.3 V logic, note that the MAX232EIDW requires a 5 V supply for the charge-pump to generate RS232-level outputs; a level translator on the logic side may be needed.

Frequently asked questions

What is the equivalent of MAX232EIDW?

The MAX232EIDW is part of the broad MAX232 family. A common variant is the MAX232EIDWR, which differs only in tape-and-reel packaging versus the tube shipment of the MAX232EIDW. Both share the same die, pinout, and 16-SOIC footprint, so the IDWR is a drop-in alternative for reel-fed assembly lines.

Is MAX232EIDW RoHS compliant?

Yes, the MAX232EIDW is ROHS3 compliant, meeting the latest EU restriction-of-hazardous-substances directive. No exemption declarations are needed for shipping into regulated markets.
