description/ordering information
The SN74HC74 device contains 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.

This configuration is nonstable; that is, it does not
persist when PRE or CLR returns to its inactive
