What this isolator delivers
The MAX14936DAWE+ is a 4-channel, unidirectional digital isolator using capacitive coupling for 5000Vrms isolation.
Channel configuration and timing
Two inputs on side 1, two on side 2 — a 2/2 split that suits bidirectional data paths like isolated SPI (SCLK and MOSI one way, MISO the other) or general-purpose I/O isolation. Propagation delay is 54.1 ns typical on the low-to-high edge and 55.3 ns on high-to-low, with pulse-width distortion capped at 4.5 ns. Rise and fall times are a fast 2 ns typical, so signal edges stay clean even at 1 Mbps. The 25 kV/µs common-mode transient immunity (typical) keeps data intact when large voltage transients slam across the barrier — a key spec for motor-drive or inverter environments where fast IGBT switching couples noise.
Housed in a 16-SOIC wide-body (0.295-inch, 7.50 mm width) — the standard footprint for reinforced isolation in industrial designs.
