SN74ACT74D datasheet by Texas Instruments

SN74ACT74D Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN74ACT74D?
  The maximum frequency of operation for the SN74ACT74D is typically 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74ACT74D is properly powered and decoupled?
  To ensure proper operation, the SN74ACT74D should be powered with a stable 5V supply, and decoupling capacitors (e.g. 0.1uF and 10uF) should be placed close to the device to filter out noise and reduce electromagnetic interference (EMI).
• What is the maximum current that the SN74ACT74D can sink or source?
  The SN74ACT74D can sink or source up to 24mA of current per output, but it's recommended to limit the current to 16mA or less to ensure reliable operation.
• How do I handle the asynchronous reset input (CLR) on the SN74ACT74D?
  The CLR input should be tied to VCC through a pull-up resistor (e.g. 1kΩ) to ensure that the flip-flops are properly reset. A capacitor (e.g. 100nF) can also be added to filter out noise on the CLR input.
• What is the propagation delay time for the SN74ACT74D?
  The propagation delay time for the SN74ACT74D is typically around 10-15ns, but it can vary depending on the specific application and operating conditions.
