DESCRIPTION
NEC's PS9814-1 and PS9814-2 is an optically coupled high
speed, isolator containing a GaAIAs LED on the input side
and a photodiode and a signal processing circuit on the output
side on one chip.
This is a plastic S08 type for high density applications.

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 conrm the characteristics during
power up and power down, before using this device.
