74HC74DB,112 datasheet by NXP Semiconductors

74HC74DB,112 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the 74HC74DB,112?
  The recommended operating voltage range for the 74HC74DB,112 is 2.0 V to 6.0 V, with a typical voltage of 5.0 V.
• How do I handle the power-up and power-down sequences for the 74HC74DB,112?
  It is recommended to power up the VCC pin first, followed by the input signals, and power down the input signals first, followed by the VCC pin to prevent latch-up or damage to the device.
• What is the maximum frequency of operation for the 74HC74DB,112?
  The maximum frequency of operation for the 74HC74DB,112 is 100 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure that the 74HC74DB,112 is properly decoupled from the power supply?
  It is recommended to use a 0.1 μF to 1 μF decoupling capacitor between the VCC pin and GND pin, as close to the device as possible, to filter out noise and ensure stable operation.
• What is the maximum current that the 74HC74DB,112 can sink or source?
  The maximum current that the 74HC74DB,112 can sink or source is 25 mA per output pin, but this can vary depending on the specific application and operating conditions.
