Product details

Digital isolator for industrial signal isolation

The MAX14931EASE+T is a four-channel general-purpose digital isolator from Maxim Integrated, built with capacitive coupling technology. It provides 2750Vrms isolation between input and output, with a 25Mbps data rate across unidirectional channels arranged in a 3/1 side-1/side-2 split.

2750Vrms isolation with 25kV/µs CMTI — what it means for motor drives and inverters

The 2750Vrms isolation rating covers basic insulation for 240VAC mains-referenced circuits. The real differentiator is the 25kV/µs typical common-mode transient immunity.

Active production — no LTB risk

Lifecycle status is Active with no end-of-life notice. The part is RoHS3 compliant. For a BOM line that needs a known-good digital isolator without a looming last-time-buy, this one stays in the supply chain.

Frequently asked questions

What is the price of MAX14931EASE+T?

Pricing is confirmed at quote time through independent distribution. Submit an RFQ for current market pricing on your target quantity.

Is MAX14931EASE+T available via RFQ confirmation?

Availability is confirmed at quote time. This part is sourced to order through independent distribution; submit an RFQ for current stock status and lead time.

What is the difference between MAX14931EASE+T and MAX14930EASE+T?

The MAX14931EASE+T has a 3/1 channel split (three inputs on side 1, one on side 2), while the MAX14930EASE+T uses a 4/0 split (all four inputs on side 1). Both are 4-channel, 25Mbps, 2750Vrms isolators in the same package. Choose the 3/1 variant when you need a reverse-direction channel for SPI MISO or a feedback signal.

Is MAX14931EASE+T suitable for SPI isolation?

Yes. The 3/1 channel split maps directly to SPI: SCLK, MOSI, and CS on side 1, MISO on side 2. The 25Mbps data rate and 27.5ns/28.8ns propagation delay are fast enough for most SPI buses up to 20MHz.
