DESCRIPTION
The HEF4013B is a dual D-type flip-flop which features
independent set direct (S
D
), clear direct (C
D
), clock inputs
(CP) 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 D or 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.
