Frequently Asked Questions
What type of flip-flop is the 74HC/HCT574?
It is an octal D-type, positive edge-triggered, 3-state flip-flop.
How do I enable or disable the outputs?
Use the OE (3-state output enable) input. LOW enables it, and HIGH puts the outputs in high impedance OFF-state.
What is the typical maximum operating frequency for this component?
For 74HC, it's 133 MHz; for 74HCT, it’s 24 MHz.
What determines the dynamic power dissipation (PD)?
The formula is PD = C × V × f + Σ(C × V × f).
Are there any functional differences between revisions?
Functionally, the “574” is identical to the “374”, but it has a different pinning.
