CD74HC251E Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the CD74HC251E is 25 MHz, but it can vary depending on the supply voltage and operating conditions.
  • To ensure proper power supply, connect VCC to a 2.0-V to 6.0-V power supply, and GND to a ground connection. Also, decouple the power supply with a 0.1-μF capacitor to reduce noise and ensure stable operation.
  • The maximum input voltage that the CD74HC251E can handle is 6.0 V, which is the maximum rating for the device. Exceeding this voltage can cause damage to the device.
  • Unused inputs on the CD74HC251E should be tied to a logic level (either VCC or GND) to prevent them from floating and causing unintended behavior.
  • Yes, the CD74HC251E is compatible with 5-V logic, but it can also operate at lower voltages down to 2.0 V. However, the output voltage levels may not be compatible with 5-V logic at lower supply voltages.
