HEF4013BT
DESCRIPTION
The HEF4013B is a dual D-type flip-flop which features
independent set direct (SD), clear direct (CD), 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 (CD) and set-direct (SD) 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
