CD74HC393M datasheet by Texas Instruments

CD74HC393M Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HC393M can handle?
  The CD74HC393M can handle clock frequencies up to 30 MHz.
• How do I ensure that the CD74HC393M is properly powered?
  The CD74HC393M 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 CD74HC393M?
  The propagation delay time of the CD74HC393M is typically around 15 ns, but it can vary depending on the operating conditions and the specific application.
• Can I use the CD74HC393M in a 3.3 V system?
  Yes, the CD74HC393M is compatible with 3.3 V systems, but it is recommended to check the voltage tolerance of the specific system and ensure that the CD74HC393M is operated within its recommended operating conditions.
• How do I reset the CD74HC393M?
  The CD74HC393M has an asynchronous reset input (MR) that can be used to reset the counter. The reset input is active-low, meaning that it must be pulled low to reset the counter.
