CD74HC393E datasheet by Texas Instruments

CD74HC393E Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HC393E can handle?
  The CD74HC393E can handle clock frequencies up to 25 MHz.
• How do I ensure that the CD74HC393E is properly powered?
  The CD74HC393E requires a power supply voltage (VCC) of 2.0 V to 6.0 V, and it is recommended to decouple the power supply with a 0.1 μF capacitor.
• What is the propagation delay time of the CD74HC393E?
  The propagation delay time of the CD74HC393E is typically around 15 ns, but it can vary depending on the operating conditions and the specific application.
• Can I use the CD74HC393E in a 3.3 V system?
  Yes, the CD74HC393E is compatible with 3.3 V systems, but it is recommended to check the voltage tolerance of the specific device and the system requirements.
• How do I reset the CD74HC393E counter?
  The CD74HC393E has a asynchronous reset input (MR) that can be used to reset the counter to zero. The reset input is active-low, meaning it must be pulled low to reset the counter.
