CD74HCT563E datasheet by Texas Instruments

CD74HCT563E Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD74HCT563E?
  The recommended operating voltage range for the CD74HCT563E is 4.5V to 5.5V, although it can operate down to 3.5V with reduced performance.
• How do I ensure proper power sequencing when using the CD74HCT563E?
  To ensure proper power sequencing, the VCC pin should be powered up before the input signals, and the input signals should be stable before the clock signal is applied.
• What is the maximum clock frequency that the CD74HCT563E can handle?
  The maximum clock frequency that the CD74HCT563E can handle is 30 MHz, although this may vary depending on the specific application and operating conditions.
• Can I use the CD74HCT563E in a 3.3V system?
  Yes, the CD74HCT563E can be used in a 3.3V system, but the output voltage levels may not be compatible with 3.3V logic. A level translator or voltage regulator may be required to ensure proper operation.
• How do I handle unused inputs on the CD74HCT563E?
  Unused inputs on the CD74HCT563E should be tied to VCC or GND through a pull-up or pull-down resistor to prevent floating inputs and ensure proper operation.
