description/ordering information

The ’HC74 devices contain two independent

D-type positive-edge-triggered flip-flops. A low

levelatthepreset(PRE)orclear(CLR)inputssets

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.
