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.

Notes

1. H = HIGH state (the more positive voltage)

L = LOW state (the less positive voltage)

X = state is immaterial

= positive-going transition

On + 1 = state after clock positive transition
