SN74HC174PWR datasheet by Texas Instruments

SN74HC174PWR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HC174PWR can handle?
  The maximum clock frequency of the SN74HC174PWR is 25 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74HC174PWR is properly powered and decoupled?
  To ensure proper power and decoupling, use a 5V power supply, add a 0.1uF decoupling capacitor between VCC and GND, and use a 10uF bulk capacitor for each power pin.
• What is the maximum current that the SN74HC174PWR can sink or source?
  The SN74HC174PWR can sink or source up to 25mA per output pin, but it's recommended to limit the current to 10mA per pin to ensure reliable operation.
• How do I handle the asynchronous reset input (MR) of the SN74HC174PWR?
  The asynchronous reset input (MR) should be tied to VCC through a 1kΩ resistor and a 0.01uF capacitor to ensure proper reset operation.
• What is the propagation delay of the SN74HC174PWR?
  The propagation delay of the SN74HC174PWR is typically around 10ns, but it can vary depending on the specific application and operating conditions.
