CD74HCT75M datasheet by Texas Instruments

CD74HCT75M Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HCT75M can handle?
  The CD74HCT75M can handle clock frequencies up to 30 MHz.
• How do I ensure that the CD74HCT75M is properly powered?
  The CD74HCT75M requires a power supply voltage of 4.5V to 5.5V, 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 CD74HCT75M?
  The propagation delay of the CD74HCT75M is typically around 10ns to 15ns, depending on the operating conditions and load capacitance.
• Can I use the CD74HCT75M in a 3.3V system?
  Yes, the CD74HCT75M can operate at 3.3V, but the output voltage levels may not be compatible with 3.3V logic. It is recommended to use a level translator or a voltage regulator to ensure compatibility.
• How do I handle the asynchronous reset input (MR) of the CD74HCT75M?
  The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure that the device is properly reset. A capacitor (e.g., 100nF) can be added in parallel to the pull-up resistor to filter out noise.
