CD4013BMCD4013BC Dual D Flip-Flop

General Description

The CD4013B dual D flip-flop is a monolithic complementa-

ry 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 regis-

ter 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
