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 VDD power supply range of 3 V to 15 V referenced to VSS

(usually ground). Unused inputs must be connected to VDD, VSS, or another input.
