HEF4013B
Dual D-type flip-flop

Product 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 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. The
device is suitable for use over both the industrial (−40 °C to +85 °C) and automotive
(−40 °C to +125 °C) temperature ranges.
