1See figure 1 for explicit timing delays.

2Typical data are for initial design estimations only, and assume optimum manufacturing and application conditions, such as TA = 25°C. Performance

may vary for individual units, within the specified maximum and minimum limits.

3Power-On Time is the elapsed time after the voltage on the ¯S¯¯L¯¯E¯¯E¯¯P¯ pin exceeds the active mode threshold voltage,VINH, until the time the device output

reaches 90% of its value. When the device output is loaded with the maximum capacitance of 10 nF, the Power-On Time range is guaranteed for input

¯S¯¯L¯¯E¯¯E¯¯P¯ pin frequencies less than 10 Hz.

4Power-Off Time is the duration of time between when the signal on the ¯S¯¯L¯¯E¯¯E¯¯P¯ pin switches from HIGH to LOW and when ICC drops to under 100 μA.

During this time period, the output goes into the HIGH impedance state.
