NCP302 and NCP303 series are measured with a 10 pF capacitive load. NCP303 has an additional 470 k pullup resistor

connected from the reset output to +5.0 V. The reset output voltage waveforms are shown for the active low ‘L’ devices. Output

time delay tD1 and tD2 are dependent upon the delay capacitance. Refer to Figures 30, 31, and 32. The upper detector

threshold, VDET+ is the sum of the lower detector threshold, VDET− plus the input hysteresis, VHYS.
