It provides 2500Vrms isolation between input and output sides, with a data rate of 1Mbps and propagation delay of 100ns max. The supply range spans 2.7V to 5.5V on both sides, making it compatible with 3.3V and 5V logic without extra level translation. Three channels drive from Side 1 to Side 2; one channel drives the opposite direction, which suits mixed-direction signal isolation in industrial interfaces like SPI or UART. ## Active lifecycle — no LTB urgency on this line ROHS3 compliant per the listing. For a production BOM that needs a standard 4-channel isolator in a 16-SOIC wide-body footprint, this part is still the manufacturer's current offering — no need to chase a discontinued alternate or stockpile date codes. The channel assignment — three forward, one reverse — is the key selection differentiator within the ADUM140x family. The ADUM1400 (4/0) is all forward; the ADUM1402 (2/2) is split equally. The 3/1 split of the ADUM1401 matches designs where most signals go one way (e.g., SPI with MISO, MOSI, SCLK plus a single reverse-direction chip-select or IRQ line). If your application needs more reverse channels, the ADUM1411 (3/1 with 3750Vrms isolation) or ADUM1410 (4/0) are pin-compatible alternatives in the same 16-SOIC package, same 1Mbps speed grade. ## Common-mode transient immunity and pulse-width distortion Rated at 25kV/µs minimum common-mode transient immunity, the ADUM1401 handles the noise edges typical in motor-drive and inverter environments without false toggling. Pulse-width distortion is specified at 40ns max, and rise/fall times are 2.5ns typical — clean enough for 1Mbps signalling with adequate eye margin.","metaTitle":"ADUM1401ARWZ-RL iCoupler Digital Isolator, 2500Vrms, 1Mbps","metaDescription":"ADUM1401ARWZ-RL 4-channel magnetic isolator, 2500Vrms isolation, 1Mbps data rate, 2.7V-5.5V supply.
