It supports CAN, RS422, RS485, and SPI protocols across its four unidirectional channels (4 inputs on side 1, 0 on side 2). Maximum propagation delay is 9.2 ns (tpLH) and 9.4 ns (tpHL), with pulse-width distortion capped at 2 ns. These numbers keep the timing budget tight for high-speed SPI at 200 Mbps and for CAN FD where bit timing margins are already squeezed. Common-mode transient immunity is a minimum of 50 kV/µs — critical when the isolator sits across a motor-drive or inverter ground bridge where fast switching edges try to couple through the barrier. The 0.8 ns / 1 ns rise/fall times (max) preserve signal integrity on short PCB traces. ## Package and supply flexibility Housed in a 20-SSOP package (0.209\", 5.30 mm width), surface-mount only. The supply range from 1.71V to 5.5V covers 1.8V, 2.5V, 3.3V, and 5V logic rails without needing a separate level shifter — a single part bridges a 1.8V MCU SPI to a 5V CAN transceiver, for instance. No isolated power is generated on-chip; the part is a signal isolator only, so each side needs its own supply.","metaTitle":"MAX22344CAAP+ 4-Channel Digital Isolator, 200 Mbps","metaDescription":"MAX22344CAAP+ 4-channel capacitive-coupling isolator supports CAN, RS422, RS485, SPI at 200 Mbps. 3750 Vrms isolation, 50 kV/µs CMTI, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"CAN, RS422, RS485, SPI","Package":"Tube","Data Rate":"200Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.71V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"4/0","Rise / Fall Time (Typ)":"0.8ns, 1ns (Max)","Supplier Device Package":"20-SSOP","Pulse Width Distortion (Max)":"2ns","Propagation Delay tpLH / tpHL (Max)":"9.2ns, 9.4ns","Common Mode Transient Immunity (Min)":"50kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.07","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.07000","currency":"USD"},{"qty":10,"price":"$6.38600","currency":"USD"},{"qty":25,"price":"$6.08840","currency":"USD"},{"qty":100,"price":"$5.28660","currency":"USD"},{"qty":250,"price":"$5.04900","currency":"USD"},{"qty":500,"price":"$4.60350","currency":"USD"},{"qty":1000,"price":"$4.45500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/625eb2d22a4aae01fed00154d9d27828.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX22344CAAP+ compatible with CAN FD?","answer":"Yes, the 200 Mbps data rate and 9.2 ns / 9.4 ns propagation delay are well within CAN FD timing requirements (typically 5 Mbps to 10 Mbps), so the isolator will not bottleneck the bus. The 50 kV/µs CMTI also helps reject common-mode noise from the CAN transceiver's differential bus."},{"question":"Can MAX22344CAAP+ be used with a 5V supply?","answer":"Yes, the supply range is 1.71V to 5.5V, so 5V operation is within spec on both sides.
