ULQ2436M, COUNTDOWN POWER TIMER

OSC.

An external resistor in the range of 200 kΩ to 2 MΩ and an external capacitor in the range of 0.001 µF to 1 µF determine the frequency of the internal oscillator.

The period of oscillation is nominally RTCT with the overall output time period (after the digital countdown) of t = 4064 RTCT where
