SN74HCT74DR Frequently Asked Questions (FAQ)
-
The maximum clock frequency of the SN74HCT74DR is 30 MHz, but it can vary depending on the specific application and operating conditions.
-
To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to a valid logic level during power-up. You can also use an external reset circuit to initialize the flip-flops.
-
The recommended operating voltage range for the SN74HCT74DR is 4.5V to 5.5V, with a typical voltage of 5V.
-
The preset and clear inputs are asynchronous, meaning they can be asserted at any time, including during clock transitions. Ensure that these inputs are synchronized with the clock signal to avoid metastability issues.
-
The propagation delay time for the SN74HCT74DR is typically around 10-15 ns, but it can vary depending on the specific application and operating conditions.
