This margin reduces the chance of bit errors when the cable runs through electrically noisy environments like motor drives or switching power supplies. Full-duplex operation means the driver and receiver paths are independent, so the part handles simultaneous transmit and receive without external direction control. ## Package, temperature grade, and supply posture The supplier device package is also 16-SSOP, so the PCB footprint matches standard SSOP-16 land patterns.","metaTitle":"MAX3221ECAE+T RS-232 Transceiver, 250 kbps, 16-SSOP","metaDescription":"Analog Devices MAX3221ECAE+T RS-232 transceiver, full duplex, 1/1 driver/receiver, 250 kbps, 3V-5.5V supply, 16-SSOP.
