Dual JK flip-flop Rev. 9 - 18 November 2011 Product data sheet 1. General description The HEF4027B is a edge-triggered dual JK flip-flop which Features independent set-direct (SD), clear-direct (CD), clock (CP) inputs and outputs (Q, Q). Data is accepted when CP is LOW, and transferred to the output on the positive-going edge of the clock. The active HIGH asynchronous clear-direct (CD) and set-direct (SD) inputs are independent and override the J, K, and CP inputs. The outputs are buffered for best system performance. Schmitt trigger action makes the clock input highly tolerant of slower rise and fall times. It operates over a remended VDD power supply range of 3 V to 15 V...
