1. Maximum values include unavoidable inaccuracies of the industrial tests.

2. TPHL is measured when the output signal crosses a voltage level at 50% of VCC with the following conditions: inverting

input voltage (IN-) = VICM and non-inverting input (IN+), moving from VICM + 100mV to VICM - overdrive.

3. TPLH is measured when the output signal crosses a voltage level at 50 % of VCC with the following conditions: inverting

input voltage (IN-) = VICM and non-inverting input (IN+), moving from VICM - 100 mV to VICM + overdrive.
