CD74HCT640M Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the CD74HCT640M is 50 MHz.
  • Yes, the CD74HCT640M is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 4.5V to 5.5V supply voltage.
  • The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the outputs. When OE is high, the outputs are in a high-impedance state.
  • The propagation delay of the CD74HCT640M is typically around 10 ns, but it can vary depending on the operating conditions and load capacitance.
  • No, the CD74HCT640M is not compatible with 3.3V systems. It's designed to operate at 4.5V to 5.5V supply voltage.
