Product details

What this isolator does and where it fits

The MAX14931CAWE+ is a 4-channel, unidirectional digital isolator using capacitive coupling to provide galvanic isolation up to 2750 Vrms. It supports a data rate of 150 Mbps with typical propagation delays of 7.5 ns and pulse-width distortion under 1 ns.

Key ratings and what they mean for your BOM

The 150 Mbps data rate sets the ceiling for serial data across the barrier. The 2750 Vrms isolation is a 1-minute withstand rating. Common-mode transient immunity of 25 kV/µs keeps data integrity in variable-frequency drive applications.

Lifecycle and sourcing posture

The MAX14931CAWE+ is an active product with no end-of-life notice. It is ROHS3 compliant. For current pricing and lead time, submit an RFQ through this listing.
