|---|---|
| Type | Transceiver |
| Mounting | Surface Mount |
| Supply voltage | 3V ~ 5.5V |
| Protocol | RS232 |
| Operating temperature | 0°C~70°C |
| Duplex | Full |

The 300 mV receiver hysteresis helps reject noise on longer cable runs without external filtering.
If your design sees -40°C, look at the industrial-temperature variants in the MAX3222 family.
ROHS3 compliant, so it fits lead-free assembly lines without exemption paperwork.
The MAX3222ECPWR supports data rates up to 500 kbps.
The MAX3222ECPWR is the tape-and-reel variant of the base MAX3222E in the 20-TSSOP package; pinout and function are identical. The 'PWR' suffix indicates the reel packaging, not a functional difference.
