CD74HCT299M datasheet by Texas Instruments

CD74HCT299M Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HCT299M can handle?
  The CD74HCT299M can handle clock frequencies up to 40 MHz.
• How do I ensure that the CD74HCT299M is properly powered?
  The CD74HCT299M requires a power supply voltage (VCC) 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 maximum input voltage that the CD74HCT299M can tolerate?
  The CD74HCT299M can tolerate input voltages up to 7V without damage, but it is recommended to keep input voltages within the specified operating range of 0V to VCC to ensure proper operation.
• How do I handle the asynchronous reset input (MR) of the CD74HCT299M?
  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 low-going pulse on the MR input will reset the device.
• What is the propagation delay of the CD74HCT299M?
  The propagation delay of the CD74HCT299M is typically around 10ns to 20ns, depending on the operating conditions and load capacitance.
