APPLICATION INFORMATION  
By changing the time constant C1 and, the response, attack and release time, may be varied. In the above  
application conditions, power dissipation may be operated at higher levels than the absolute maximum ratings.  
The wattage of R is to be determined by the total LED current and R value recommended by the R table.  
VCC  
VCC=10~16V; R=100  
VCC= 8~14V; R=68Ω  
VCC=6.5~12V; R=47Ω
