CD74HCT564M datasheet by Texas Instruments

CD74HCT564M Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD74HCT564M?
  The recommended operating voltage range for the CD74HCT564M is 4.5V to 5.5V, although it can operate down to 3.5V with reduced performance.
• How do I handle the unused inputs on the CD74HCT564M?
  Unused inputs on the CD74HCT564M should be tied to VCC or GND to prevent floating inputs, which can cause unpredictable behavior.
• What is the maximum clock frequency that the CD74HCT564M can handle?
  The maximum clock frequency that the CD74HCT564M can handle is 30 MHz, although this can vary depending on the specific application and operating conditions.
• Can I use the CD74HCT564M in a 3.3V system?
  Yes, the CD74HCT564M can be used in a 3.3V system, but it may not meet the full specifications listed in the datasheet. It's recommended to review the datasheet and perform thorough testing to ensure compatibility.
• How do I ensure that the CD74HCT564M is properly powered up and initialized?
  To ensure proper power-up and initialization, it's recommended to follow the power-up sequence outlined in the datasheet, which typically involves applying power to VCC before applying clock and input signals.
