DEFINITION OF OUTPUT DELAY TIME
Output Delay Time tPLH is defined as follows:
1. In the case of Nch Open Drain Output:
Under the condition of the output pin (OUT) is pulled up through a resistor of 470kΩ to 5V, the time interval
between the rising edge of VDD pulse from 0.85V to (+VDET)+ 1.0V and becoming of the output voltage to 2.5V.
2. In the case of CMOS Output:
The time interval between the rising edge of VDD pulse from 0.85V to (+VDET)+ 1.0V and becoming of the
output voltage to (VDD/2) V.
