CD74HC123E Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the CD74HC123E is 10 MHz.
  • Yes, the CD74HC123E is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
  • The reset pin (MR) should be tied to VCC through a pull-up resistor (e.g., 1 kΩ) to ensure proper operation. A capacitor (e.g., 10 nF) can be added in parallel to filter out noise.
  • The enable input (EN) allows the oscillator to be enabled or disabled. When EN is low, the oscillator is enabled, and when EN is high, the oscillator is disabled.
  • Yes, the CD74HC123E can operate in a 3.3V system, but the output frequency will be lower than in a 5V system. Consult the datasheet for specific frequency vs. voltage characteristics.
