NCP304 ON, NCP304 Datasheet - Page 7

• Manufacturer Part Number: NCP304
• Description: Voltage Detector Series
• Manufacturer: ON

NCP304 and NCP305 series are measured with a 10 pF capacitive load. NCP305 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. The upper detector
