CD4045BE Frequently Asked Questions (FAQ)

  • The recommended operating voltage range for the CD4045BE is 4.5V to 15V.

  • To ensure the oscillator starts reliably, a 1kΩ to 10kΩ resistor should be connected between the oscillator pins (pins 11 and 12) and a 10nF to 100nF capacitor should be connected between the oscillator pin (pin 11) and ground.

  • The maximum frequency of operation for the CD4045BE is approximately 1MHz.

  • To synchronize the CD4045BE with an external clock signal, connect the external clock signal to the clock input pin (pin 1) and set the oscillator disable pin (pin 13) to a logic high level.

  • The VDD pin (pin 16) is the power supply pin for the internal logic circuits and should be connected to a stable voltage source.
