The CD4013B dual D 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.
Wide supply voltage range 3.0V to 15V
