Dual JK flip-flop
The HEF4027B is a dual positive-edge triggered JK flip-flop featuring independent set direct (nSD), clear direct (nCD), clock inputs (nCP) and complementary outputs (nQ and nQ). Data is accepted when nCP is LOW, and transferred to the output on the positive-going edge of the clock. The asynchronous clear-direct (nCD) and set-direct (nSD) are independent and override the nJ, nK, and nCP inputs. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VDD.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples. Check out the list of official distributors.
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.
