FOD0721, FOD0720, FOD0710 — High CMR, 25Mbit/sec Logic Gate Optocoupler www.DataSheet4U.com May 2008 FOD0721, FOD0720, FOD0710 High CMR, 25Mbit/sec Logic Gate Optocoupler Features ■ 20kV/µs minimum CMR ■ 40ns max. propagation delay ■ Data Rate, Non-Return Zero Coding Description The FOD0721/0720/0710 family utilizes Fairchild’s patented coplanar packaging technology, Optoplanar®, and optimized IC design to guarantee minimum 20kV/µs Common Mode Noise Rejection (CMR) rating. These high-speed logic gate optocouplers consist of a high-speed AlGaAs LED driven by a CMOS IC coupled to a CMOS detector IC, comprising an integrated photodiode, a high-speed transimpedance amplifier and a voltage comparator with an output driver. The CMOS technology coupled to the high efficiency of the LED achieves low power consumption as well as very high speed (40ns propagation delay, 6ns pulse width distortion). These devices are available in a compact 8-pin small outline package. ■ ■ ■ ■ – 25Mbit/sec (FOD0721 and FOD0720) – 12.5Mbit/sec (FOD0710) Pulse Width Distortion – 6ns (FOD0721) – 8ns (FOD0720 and FOD0710) +5V CMOS compatibility Extended industrial temperate range – -40 to 100°C temperature range Safety and regulatory approvals – UL1577, 3750 VACrms for 1 min.
