  • Static Operation
  • Diode Protection on All Inputs
  • Supply Voltage Range = 3.0 Vdc to 18 Vdc
  • Logic Edge-Clocked Flip-Flop Design. Logic state is retained indefinitely with clock level either high or low; information is transferred to the output only on the positive-going edge of the clock pulse
  • Capable of Driving Two Low-power TTL Loads or One Low-power Schottky TTL Load Over the Rated Temperature Range. Pin-for-Pin Replacement for CD4013B.


The ON Semiconductor MC14013 (CD4013B) device consists of two identical, independent data-type flip-flops. Each flip-flop has independent data, set, reset, and clock inputs and Q and Q outputs. These devices can be used for shift register applications, and, by connecting Q output to the data input, for counter and toggle applications. The logic level present at the D input is transferred to the Q output during the positive-going transition of the clock pulse. Setting or resetting is independent of the clock and is accomplished by a high level on the set or reset line, respectively.
