FOD0738

FOD0708 Single Channel CMOS Optocoupler FOD0738 Dual Channel CMOS Optocoupler January 2006 FOD0708 Single Channel CMOS Optocoupler FOD0738 Dual Channel CMOS Optocoupler Features ■ ■ ■ ■ ■ ■ ■ ■ ■ General Description The FOD0708 and FOD0738 optocouplers consist of an AlGaAs LED optically coupled to a high speed transimpedance amplifier and voltage comparator. These optocouplers utilize the latest CMOS IC technology to achieve outstanding performance with very low power consumption. The devices are housed in a compact 8-pin SOIC package for optimum mounting density. +5 V CMOS compatibility 15 ns typical pulse width distortion 30 ns max. pulse width distortion 40 ns max. propagation delay skew High speed: 15 MBd 60 ns max. propagation delay 10 kV/µs minimum common mode rejection –40°C to 100°C temperature range UL approved (file #E90700) Applications ■ ■ ■ ■ Line receivers Pulse transformer replacement Output interface to CMOS-LSTTL-TTL Wide bandwidth analog coupling Package Dimensions 0.164 (4.16) 0.144 (3.66) SEATING PLANE Pin 1 0.202 (5.13) 0.182 (4.63) 0.019 (0.48) 0.010 (0.25) 0.006 (0.16) 0.143 (3.63) 0.123 (3.13) 0.021 (0.53) 0.011 (0.28) 0.008 (0.20) 0.003 (0.08) 0.050 (1.27) TYP 0.244 (6.19) 0.224 (5.69) Lead Coplanarity : 0.004 (0.10) MAX NC 1 8 VDD ANODE 1 1 8 VDD TRUTH TABLE LED VO, OUTPUT L H OFF ON ANODE 2 7 NC CATHODE 1 2 7 VO 1 CATHODE 3 6 VO CATHODE 2 3 6 VO 2 Note: A 0.1µF bypass capacitor must be connected between pins ...
