Product details

RS-232 transceiver for mixed-voltage serial links

The Maxim MAX3243EEAI+ is a full-duplex RS-232 transceiver with 3 drivers and 5 receivers in a 28-SSOP package. It operates from a 3V to 5.5V supply.

Supply flexibility and temperature range

The 3V to 5.5V supply range covers both 3.3V and 5V logic domains. The -40°C to +85°C temperature range suits industrial environments.

Lifecycle and compliance

It is ROHS3 compliant. For a BOM freeze or a new design, this part does not carry obsolescence risk.

Frequently asked questions

Is MAX3243EEAI+ RoHS compliant?

Yes, the MAX3243EEAI+ is ROHS3 compliant per the manufacturer's status.

What is the difference between MAX3243EEAI+ and MAX3243ECAI+?

The MAX3243EEAI+ and MAX3243ECAI+ share the same 3/5 driver/receiver count, full-duplex RS-232 protocol, and SSOP-28 package. The difference typically lies in the ESD protection level or temperature grade; check the respective datasheets for the exact delta. Both are active parts.

Can MAX3243EEAI+ operate at 3.3V?

Yes, the supply range is 3V to 5.5V, so 3.3V is well within the operating window.

Does MAX3243EEAI+ work with 5V logic?

Yes, the 3V to 5.5V supply range covers 5V operation directly.

Does MAX3243EEAI+ have an equivalent from Texas Instruments?

TI offers pin-compatible RS-232 transceivers in the same 3/5 driver/receiver configuration, such as the MAX3243E family clones. Verify the exact TI order code against your BOM for second-source qualification.
