    74HC74D,653 Frequently Asked Questions (FAQs)

    • The maximum clock frequency of the 74HC74D is 25 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
    • To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to a logic level that corresponds to the desired initial state. You can also use an external reset signal to initialize the flip-flops.
    • The recommended operating voltage range for the 74HC74D is 2.0 V to 6.0 V, with a typical voltage of 5.0 V.
    • The asynchronous reset (CLR) input should be connected to a logic level that corresponds to the desired reset state. When CLR is low, the flip-flops are reset, and when CLR is high, the flip-flops operate normally.
    • The propagation delay time for the 74HC74D is typically around 10 ns to 20 ns, depending on the operating conditions and the quality of the clock signal.
