The MAX14934FAWE+T is a 4-channel, unidirectional digital isolator from Analog Devices built on capacitive coupling technology. It is rated for 5000Vrms isolation and supports a data rate of 150Mbps.
5000Vrms isolation is the headline figure. The 150Mbps data rate is fast enough for most SPI, UART, or CAN digital isolator applications.
The MAX14934FAWE+T is available to order through independent semiconductor distributors. Submit an RFQ for current pricing and delivery lead time — availability is confirmed at quote time.
Yes, the MAX14934FAWE+T is ROHS3 compliant per the manufacturer's listing.
Within the MAX14934 series, the 2-channel (MAX14932) and 3-channel (MAX14933) variants share the same 16-SOIC package and pinout for the channels they implement. If your design requires exactly four channels, the MAX14934FAWE+T is the correct choice; a lower-channel sibling can serve as a drop-in if unused pins are left floating.
The MAX14934FAWE+T is a unidirectional isolator — all four channels drive in the same direction (Side 1 to Side 2). I2C is bidirectional, so a single MAX14934 cannot handle the data and clock lines' bidirectional nature without external circuitry. For I2C isolation, consider a dedicated bidirectional isolator or use two unidirectional channels per line with a direction-control scheme.
