MAX22444–MAX22446 Reinforced, Fast, Low-Power, Four-Channel Digital Isolators General Description The MAX22444–MAX22446 are reinforced, fast, lowpower 4-channel digital galvanic isolators using Maxim’s proprietary process technology. These devices transfer digital signals between circuits with different power domains, using as little as 0.74mW per channel at 1Mbps (1.8V supply). All of the devices in the family feature reinforced isolation for a withstand voltage rating of 5kVRMS for 60 seconds. The MAX22444–MAX22446 family offers all possible unidirectional channel configurations to accommodate any 4-channel design, including SPI, RS-485, and digital I/O applications. Output enable for the A side of the MAX22445R/S/U/V is active-low, making them ideal for isolating a port on a shared SPI bus since the CS signal can directly enable the MISO signal on the isolator. All other output enables in the MAX22444-MAX22446 fami...
