100341
Low Power 8-Bit Shift Register
General Description
The 100341 contains eight edge-triggered, D-type flip-flops
with individual inputs (P_n) and outputs (Q_n) for parallel op-
eration, and with serial inputs (D_n) and steering logic for bidi-
rectional 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 ris-
ing clock edge.
The circuit operating mode is determined by the Select in-
puts 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 kΩ pull-down resistors.
