Notes: 1. The input resistor threshold value is a resistor value from the IN-pin to ground at which the corresponding output changes its status

(fig.4)

2. ΣIIN is the sum of the IN5 to IN8 input currents.

3. The delay times are defined from the crossing point of 50% initiating signal amplitude to the crossing point of 50% output signal

amplitude
