The wide supply range from 3V to 5.5V lets it bridge 5V peripheral buses directly onto a 3.3V system rail without a separate level translator. If your application sees extended temperatures or automotive environments, look for the industrial or automotive grade variants in the same family. Housed in a 20-SSOP (0.209\", 5.30 mm width) surface-mount package, the MAX3222CDBR occupies a compact board area. Standard SSOP-20 land patterns apply; no exposed pad to route.","metaTitle":"MAX3222CDBR RS-232 Transceiver, Full Duplex, 250 kbps","metaDescription":"Texas Instruments MAX3222CDBR RS-232 transceiver, full duplex, 250 kbps data rate, 3V to 5.5V supply, 20-SSOP.
