PS9814-1, PS9814-2 Notes: 1. Typical values at TA = 25ºC 2. VOL of 2 V or more may be output if LED has a signal applied while VCC = 2.6 V or less. It is important to confi rm the characteristics during power up and power down, before using this device. 3. Test circuit for propagation delay time 4. Test circuit for common mode transient immunity.
