ONSEMI FOD0721R2 Logic Gate Optocoupler

The FOD0721R2 is a high-speed, single-channel 8-pin logic gate optocoupler utilizing Optoplanar® technology and optimized integrated circuit design. It features a high-efficiency AlGaAs LED-driven CMOS detector with an integrated photodiode, transimpedance amplifier, and voltage comparator with output driver. This configuration ensures a minimum of 20 kV/μs common-mode noise rejection (CMR). The device offers fast data transmission with a maximum propagation delay of 40 ns, pulse width distortion of 6 ns, and is compatible with 5V CMOS logic systems. Designed for applications in communications, networking, test and measurement, and industrial automation, it provides reliable electrical isolation and high-speed switching. Market demand has resulted in extended lead times, so delivery dates may fluctuate. This product is exempt from discounts.
