PHOTOTRANSISTOR OPTOCOUPLER MCT4 DS300241 8/13/01 3 OF 6 www.fairchildsemi.com NOTE: 1. The current transfer ratio (IC/IF) is the ratio of the detector collector current to the LED input current with VCE at 10 volts. 2. The frequency at which ic is 3 dB down from the 1 kHz value. 3. Rise time (tr) is the time required for the collector current to increase from 10% of its final value, to 90%. Fall time (tf) is the time required for the collector current to decrease from 90% of its initial value to 10%.
