CD74AC74M datasheet by Texas Instruments

CD74AC74M Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74AC74M can handle?
  The CD74AC74M can handle clock frequencies up to 100 MHz.
• How do I ensure that the CD74AC74M is properly powered?
  The CD74AC74M requires a power supply voltage (VCC) of 2.0V to 6.0V, and it is recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to ensure proper power supply decoupling.
• What is the propagation delay of the CD74AC74M?
  The propagation delay of the CD74AC74M is typically around 10ns to 15ns, depending on the operating conditions and load capacitance.
• Can I use the CD74AC74M in a 3.3V system?
  Yes, the CD74AC74M is compatible with 3.3V systems, but it is recommended to use a voltage regulator to ensure a stable 3.3V power supply.
• How do I handle the asynchronous reset input (MR) of the CD74AC74M?
  The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure that the flip-flop is properly reset. A low-going pulse on MR will reset the flip-flop.
