CD54HC157F Frequently Asked Questions (FAQs)

  • The maximum operating frequency of CD54HC157F is up to 100 MHz, but it depends on the input slew rate and output load capacitance.
  • The outputs of CD54HC157F should be terminated with a pull-up or pull-down resistor to prevent floating outputs. A 1 kΩ to 10 kΩ resistor is recommended.
  • Yes, CD54HC157F can be used in a 3.3V system, but the input voltage must not exceed 3.6V. Additionally, the output logic levels may not be compatible with 3.3V logic, so level translation may be required.
  • The power consumption of CD54HC157F depends on the operating frequency, input voltage, and output load. The typical quiescent current is around 10 μA, and the dynamic current is around 10 mA at 100 MHz.
  • The enable inputs (E1, E2) of CD54HC157F must be connected to a valid logic level (either VCC or GND) to ensure proper operation. Leaving them floating can cause unpredictable behavior.
