Output V OL IOL= 16mA, E VP VD =0*3 V OH EVD=EVP =0*3 IOS EVP =EVD=0*3 IGL V GL= 1.2V tp tW E ePLH EeD=0 *3 Light emitting E ePHL Hysteresis E ePLH /E ePHL Response time t PHL t PLH *7 External disturbing light illuminance E VDX *3 EeP represents illuminance of signal light in sync with the low level timing of output at GLout terminal. Fig.1 Fig.2 Fig.3 *4 Pulse cycle (t P), pulse width (t W) are defined as shown in Fig. 2. E eD represents illuminance of DC light. For detail, see Fig. 1. EVP represents illuminance of signal light in sync with the low level timing of output at GLout terminal. EVD represents illuminance of DC light. Note that the light source is CIE standard light source A. shown in Fig. 3 (Note ) Fig. 1 shows the output waveform at GL out Fig. 3. 0 Time Output waveform Ee EeD EeP at GL out terminal 5V 0V IS471F GND 280 Ω 5V 0.33 µF tW tP VCC VO GLout Light source: Infrared light emitting diode ( λ p= 940nm ) GL output MIN.
