Product details

1000Vrms isolation and 150Mbps — what that means for the BOM

The 1000Vrms isolation rating suits reinforced isolation for industrial equipment with basic insulation requirements. The 150Mbps data rate keeps up with high-speed SPI clocks and fast UART links without pulse-width distortion exceeding 1ns.

Lifecycle and sourcing reality

The MAX14131FAEE+ is listed as Active in production — no end-of-life notice, no last-time-buy window. It's ROHS3 compliant, so it passes EU material restrictions for new builds. Sourced through independent distribution and quoted to order against an RFQ.

Frequently asked questions

Can MAX14131FAEE+ be used for SPI isolation?

Yes, the 150Mbps data rate and 7.5ns propagation delay are fast enough for SPI clock rates up to 50–75 MHz, and the unidirectional channel configuration (3 inputs on side 1, 1 on side 2) matches typical SPI signals (SCLK, MOSI, MISO, CS).
