25 Mbps digital isolator with push-pull output
The FOD8001R2 is a single-channel logic-gate optoisolator from onsemi rated for 25Mbps data rate with a push-pull, totem-pole output stage. That data rate covers isolating SPI, CAN, or RS-485 links without stretching the pulse width — the 40ns max propagation delay keeps the bus timing margin intact. It provides 3750Vrms isolation and a minimum common-mode transient immunity of 20kV/µs, which means it holds its state through the fast voltage swings on a motor-drive or inverter DC bus.
The FOD8001R2 operates from either a 3V–3.6V or 4.5V–5.5V supply rail, so it interfaces directly with 3.3V MCUs and 5V logic without a level shifter. Rise and fall times are 6.5ns typical, which keeps the output edge clean enough for the 25Mbps rate without excessive ringing on a short PCB trace.
Available in Tape & Reel (TR) or Cut Tape (CT) in the 8-SOIC (0.154", 3.90mm width) package.
