HEF4013中文资料飞利浦数据手册PDF规格书

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
