Description

The 54HC74 is fabricated using a 2.5µm 5V CMOS

process and consists of two identical, independent

data type flip-flops. Each flip-flop has separate data,

set, reset, clock inputs and 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.
