100341

The 100341 contains eight edge-triggered, D-type flip-flops with individual inputs (P_n) and outputs (Q_n) for parallel operation, and with serial inputs (D_n) and steering logic for bidirectional shifting. The flip-flops accept input data a setup time before the positive-going transition of the clock pulse and their outputs respond a propagation delay after this rising clock edge.

The circuit operating mode is determined by the Select inputs S₀ and S₁, which are internally decoded to select either "parallel entry", "hold", "shift left" or "shift right" as described in the Truth Table. All inputs have 50 k Ohm pull-down resistors.
