CD74HCT257E Frequently Asked Questions (FAQs)

  • The maximum clock frequency for CD74HCT257E is 30 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
  • To ensure proper power and decoupling, use a 5V power supply, add a 0.1uF ceramic capacitor between VCC and GND, and a 10uF electrolytic capacitor between VCC and GND for bulk decoupling. Also, keep the power and ground traces short and wide.
  • No, CD74HCT257E is designed to operate with a 5V power supply. Using a 3.3V power supply may not guarantee proper operation and may lead to unpredictable behavior.
  • Unused inputs should be tied to VCC or GND through a 1kΩ resistor to prevent floating inputs and ensure proper operation.
  • The maximum current that can be sourced or sunk by the CD74HCT257E is 6mA per output pin, and 25mA total for all output pins.
