Dual JK flip-flop
HEF4027B
flip-flops
DESCRIPTION
The HEF4027B is a dual JK flip-flop which is
edge-triggered and features independent set direct
(S
D
), clear direct (C
D
), clock (CP) inputs and outputs
(O,O). 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 (C
D
) and set-direct
(S
D
) are independent and override the J, K, and CP inputs.
The outputs are buffered for best system performance.
Schmitt-trigger action in the clock input makes the circuit
highly tolerant to slower clock rise and fall times.
