Octal D-type flip-flop; positive edge-trigger; 3-state
The 74AHC574; 74AHCT574 is an 8?-?bit positive?-?edge triggered D?-?type flip?-?flop with 3?-?state outputs. The device features a clock (CP) and output enable (OE) inputs. The flip?-?flops will store the state of their individual D?-?inputs that meet the set?-?up and hold time requirements on the LOW?-?to?-?HIGH clock (CP) transition. A HIGH on OE causes the outputs to assume a high?-?impedance OFF?-?state. Operation of the OE input does not affect the state of the flip?-?flops. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
