Data Sheet

1. General description
The HEF4013B is a dual D-type flip-flop that features independent set-direct input (SD),
clear-direct input (CD), clock input (CP) and outputs (Q, Q
). Data is accepted when CP is
LOW and is transferred to the output on the positive-going edge of the clock. The active
HIGH asynchronous CD and SD inputs are independent and override the D or CP inputs.
The outputs are buffered for best system performance. The clock input’s Schmitt-trigger
action makes the circuit highly tolerant of slower clock rise and fall times.
It operates over a recommended V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V
DD
, V
SS
, or another input.
2. Features and benefits
