Additional Details

The TC74HCT174AP consists of six independent D-type flip-flops, each with its own data input (D) and a common clock (CLK) and clear (CLR) input. Data is transferred from the D input to the Q output on the positive-going transition of the clock signal. The clear input, when low, resets all flip-flop outputs (Q) to a low state, independent of the clock and data inputs. The device is typically available in a DIP-16 package. Key specifications include a typical propagation delay of around 15 ns and a quiescent current of a few microamps.
