CD74HC147E Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the CD74HC147E is 25 MHz.
  • The CD74HC147E requires a single power supply voltage (VCC) of 2.0 V to 6.0 V. Ensure that the power supply is clean and regulated, and that the voltage is within the recommended range.
  • The propagation delay time for the CD74HC147E is typically 10 ns, but can vary depending on the operating conditions and load capacitance.
  • Yes, the CD74HC147E can operate at 3.3 V. In fact, it is specified to operate from 2.0 V to 6.0 V, making it suitable for 3.3 V systems.
  • The enable inputs (E1 and E2) are active-low, meaning that they must be pulled low to enable the encoder. When E1 and E2 are high, the encoder is disabled.
