Octal D-type flip-flop with 5 V tolerant inputs/outputs; positive edge-trigger; 3-state
The 74LVC574A 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 can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.
Schmitt?-?trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.

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.
