SN74HC74QPWRQ1 datasheet by Texas Instruments

SN74HC74QPWRQ1 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HC74QPWRQ1 can handle?
  The maximum clock frequency of the SN74HC74QPWRQ1 is 25 MHz.
• How do I ensure that the flip-flops are properly initialized during power-up?
  To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to VCC or GND, and use a pull-up or pull-down resistor to prevent floating inputs.
• What is the recommended operating voltage range for the SN74HC74QPWRQ1?
  The recommended operating voltage range for the SN74HC74QPWRQ1 is 2 V to 6 V, with a typical voltage of 5 V.
• How do I handle asynchronous inputs to the flip-flops?
  Asynchronous inputs should be synchronized to the clock signal using a synchronizer circuit or a flip-flop with a clock enable input to prevent metastability issues.
• What is the maximum current that the SN74HC74QPWRQ1 can sink or source?
  The maximum current that the SN74HC74QPWRQ1 can sink or source is 25 mA per output pin.
