description/ordering information
The ’HC74 devices contain two independent
D-type positive-edge-triggered flip-flops. A low
level at the preset (PRE) or clear (CLR) inputs sets
or resets the outputs, regardless of the levels of
the other inputs. When PRE and CLR are inactive
(high), data at the data (D) input meeting the setup
time requirements are transferred to the outputs
on the positive-going edge of the clock (CLK)
pulse. Clock triggering occurs at a voltage level
and is not directly related to the rise time of CLK.
Following the hold-time interval, data at the
D input can be changed without affecting the
levels at the outputs.
