The 74ACT74 is fabricated using a 1.5µm advanced

5V CMOS process & consists of two identical,

independent data type flip-flops. Each flip-flop has

separate data, set, reset, clock inputs & Q,Q outputs.

The device can be used in Shift Register applications

and also Counter or Toggle applications by connecting

Q output to the data input. 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 clock independent and accomplished by a

high level on the respective Set or Reset line.
