SN74HC393PWR datasheet by Texas Instruments

SN74HC393PWR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HC393PWR can handle?
  The maximum clock frequency of the SN74HC393PWR is 40 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74HC393PWR 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 SN74HC393PWR can sink or source?
  The SN74HC393PWR 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 implement a reset function for the SN74HC393PWR?
  To implement a reset function, connect the MR (Master Reset) pin to a logic high level (VCC) through a pull-up resistor, and then connect it to a reset signal or a push-button switch.
• What is the propagation delay of the SN74HC393PWR?
  The propagation delay of the SN74HC393PWR is typically around 10-15ns, but it can vary depending on the specific application and operating conditions.
