The Maxim MAX3243EEAI+ is a full-duplex RS-232 transceiver with 3 drivers and 5 receivers in a 28-SSOP package.
The 3V to 5.5V supply range covers both 3.3V and 5V logic domains.
It is ROHS3 compliant.
Yes, the MAX3243EEAI+ is ROHS3 compliant per the manufacturer's status.
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.
Yes, the supply range is 3V to 5.5V, so 3.3V is well within the operating window.
Yes, the 3V to 5.5V supply range covers 5V operation directly.
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.
