Stresses exceeding the absolute maximum ratings can cause permanent damage to the device. Exposure to absolute maximum ratings for long periods of time can adversely affect reliability. Note: A ceramic capacitor (.1 µf) should be connected between pin 6 and pin 4 to stabilize the operation of a high gain linear amplifier. Otherwise, this Photocoupler may not switch properly. The bypass capacitor should be placed within 1 cm of each pin. 4.2 Recommended Operating Conditions Parameter Symbol Min Max Unit Operating Temperature T A -4 1 o C Supply Voltage V CC V Output Voltage V O 3 V Input Current (ON) I FL(ON) 1 2 ma Input Voltage (OFF) V F(OFF) -5.8 V 4/12 Part No. :
