The MAX3221EEAE+ is a single-channel RS-232 transceiver in a 16-SSOP package, handling one driver and one receiver for full-duplex serial communication at 250 kbps.
The MAX3221EEAE+ carries an Active lifecycle status — no last-time-buy or obsolescence risk for new designs. It is ROHS3 compliant.
Yes, the supply voltage range of 3V to 5.5V covers 3.3V rails directly. No level translation is required between a 3.3V UART and the RS-232 line.
The MAX3221EEAE+ is a Maxim part with a 1/1 driver/receiver count in a 16-SSOP package. Other RS-232 transceivers in the same package family (e.g., from TI or ADI) may be pin-compatible but should be verified against the specific pinout and supply range — no universal drop-in is guaranteed without checking the datasheet.
