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 470k

Ω to 5V, the time interval

between the rising edge of V

DD pulse from 0.55V to (−VDET)+2.0V or the time interval of 6.0V pulse voltage is

supplied, the becoming of the output voltage to 2.5V.

2. In the case of CMOS Output:

The time interval between the rising edge of V

DD pulse from 0.55V to (−VDET)+2.0V or the time interval of 6.0V

pulse voltage is supplied, the becoming of the output voltage to ((

−VDET)+2.0V)/2 or 3.0V.
