1. Hysteresis is a built-in feature of the TS3121. It is defined as the voltage difference between the trip points.

2. Maximum high-level output leakage current at T = 25 °C is guaranteed by design.

3. tPLH is measured when the output signal crosses a voltage level at 50% of Vcc with the following conditions: inverting inputvoltage (IN-) =

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

4. tPHL is measured when the output signal crosses a voltage level at 50% of Vcc with the following conditions: inverting inputvoltage (IN-) =

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