Parts, tools and supplies for the electronics experimenter.
The SN74HC74 has two independent D-type positive-edge-triggered flip-flops with preset and clear functions. 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 are transferred to the outputs on the positive-going edge of the clock (CLK) pulse.
