Description
Fairchild Semiconductor
Dual D-type Flip-flop
The CD4013B dual D-type flip-flop is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement mode transistors. 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.

Note 2: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed, they are not meant to imply that the devices should be operated at these limits. The tables of “Recommended Operating Conditions” and “Electrical Characteristics” provide conditions for actual device operation. Note 3: VSS = 0V unless otherwise specified.
