It handles one driver and one receiver in full-duplex mode at 250 kbps. ## Lifecycle and sourcing It is ROHS3 compliant. If you need a second source or a pin-compatible alternate, the MAX3221ECAE (without the + suffix) is the same die in the same package — the + just marks lead-free finish, so it is a drop-in swap for existing BOMs.","metaTitle":"MAX3221ECAE+ RS-232 Transceiver, 250 kbps, 3V-5.5V, 16-SSOP","metaDescription":"Maxim MAX3221ECAE+ RS-232 transceiver, full duplex 1/1 driver/receiver, 250 kbps, 3V to 5.5V supply, 16-SSOP.
