| FOD0708 Single Channel CMOS Optocoupler FOD0738 Dual Channel CMOS Optocoupler April 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/s minimum common mode rejection -40C to 100C 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 H L OFF ON ANODE 2 7 NC CATHODE 1 2 7 VO 1 CATHODE 3 6 VO CATHODE 2 3 6 VO 2 Note: A 0.1F bypass capacitor must be connected between pins 5 and 8.

Propagation delay time, high to low (tPHL), is measured from the 50% level on the rising edge of the input pulse to the 2.5V level of the falling edge of the output voltage signal. Propagation delay time, low to high (tPLH), is measured from the 50% level on the falling edge of the input pulse to the 2.5V level of the rising edge of the output voltage signal. 2. Pulse width distoration is defined as the absolute difference between the high to low and low to high propagation delay times, | tPHL - tPLH |. 3. Propagation delay skew, tPSK, is defined as the worst case difference in tPHL or tPLH between units within the recommended operating range of the device. 4. CMH - The maximum tolerated rate of rise of the common mode voltage to ensure the output will remain in the high state, (i,e., VOUT > 2.0V) Measured in kilovolts per microsecond (kV/s). 5. CML - The maximum tolerated rate of fall of the common mode voltage to ensure the output will remain in the low state, (i,e., VOUT < 0.8V). Measured in kilovolts per microsecond (kV/s). 6. Isolation voltage, VISO, is an internal device dielectric breakdown rating. For this test, pins 1,2,3,4 are common, and pins 5,6,7,8 are common. 3 FOD0708/FOD0738 Rev. 1.0.7 www.fairchildsemi.com FOD0708 Single Channel CMOS Optocoupler FOD0738 Dual Channel CMOS Optocoupler Typical Characteristics Figure 1.
