The MAX14930AASE+ is a general-purpose digital isolator using capacitive coupling across a 2750Vrms barrier. Four unidirectional channels — three on side 1, one on side 2 — handle data at up to 1Mbps with typical rise/fall times of 2ns.
No NRND or last-time-buy notice is on record.
Both are quad-channel digital isolators in 16-SOIC, but the ADuM1400 uses iCoupler magnetic coupling and typically offers higher data rates (10Mbps or more). The MAX14930AASE+ uses capacitive coupling and is rated for 1Mbps. Pinouts may differ — verify the pin-to-pin mapping against your layout before substituting.
Yes. The supply range on each side is 1.71V to 5.5V, so 1.8V logic is directly compatible without an external level translator.
Yes, it is ROHS3 compliant.
Within the Maxim MAX14930 family, the MAX14931AASE+ adds a fourth channel on side 2 (4/0 vs 3/1 input/output configuration). Both share the same 16-SOIC package and 2750Vrms isolation, but the channel direction mapping differs — check the side 1 / side 2 assignment before swapping.
