CD54HCT164F3A datasheet by Texas Instruments

CD54HCT164F3A Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD54HCT164F3A?
  The recommended operating voltage range for CD54HCT164F3A is 4.5V to 5.5V, although it can operate down to 3V with reduced performance.
• How do I handle the unused inputs on the CD54HCT164F3A?
  Unused inputs on the CD54HCT164F3A should be tied to VCC or GND to prevent floating inputs, which can cause excessive power consumption and noise.
• What is the maximum clock frequency that the CD54HCT164F3A can handle?
  The maximum clock frequency that the CD54HCT164F3A can handle is 30 MHz, although this can vary depending on the specific application and operating conditions.
• Can I use the CD54HCT164F3A in a 3.3V system?
  Yes, the CD54HCT164F3A can be used in a 3.3V system, but the output voltage levels may not be fully compatible with 3.3V logic. A voltage translator or level shifter may be required.
• How do I ensure that the CD54HCT164F3A is properly powered on and off?
  To ensure proper power-on and power-off sequencing, the VCC pin should be powered on before the clock signal, and the clock signal should be disabled during power-off.
