So that R 1 and R 2 is determined. ( 2 ) Set for Input Resistance Set Ri on output impedance ( usually 75 ) of a mounting equipment. ( 3 ) Set for R E When there is no signal ( input signal : 0 ) , set I LED flowed into infrared LED on 10 mA. ( 4 ) Set for Low Cut-off Frequency Low cut-off frequency with C terminal capacitance, C C , is represented by the following formula ; f C = 100/C C ( Hz ) ( C C : F value ) Then set Ci with input impedance of by-pass diode on as much value as possible on condition that f C >1/ ( 2 CiR ) [R = R 1 R2 / ( R1 + R 2 ) ] s Precautions for Use ( 1 ) It is recommended that a by-pass capacitor of more than 0.01 F is added between V CC and GND near the device in order to stabilize power supply line. ( 2 ) Handle this product the same as with other integrated circuits against static electricity. ( 3 ) As for other general cautions, refer to the chapter " Precautions for Use " |
