Product Summary

 ’HC74 devices contain two independentD-type positive-edge-triggered flip-flops. A lowlevel at the preset (PRE) or clear (CLR) inputs setsor resets the outputs, regardless of the levels ofthe other inputs. When PRE and CLR are inactive(high), data at the data (D) input meeting the setuptime requirements are transferred to the outputson the positive-going edge of the clock (CLK)pulse. Clock triggering occurs at a voltage leveland is not directly related to the rise time of CLK.Following the hold-time interval, data at theD input can be changed without affecting thelevels at the outputs
