100341
Low Power 8-Bit Shift Register
General Description
The 100341 contains eight edge-triggered, D-type flip-flops
with individual inputs (Pn) and outputs (Qn) for parallel
operation, and with serial inputs (Dn) 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 kΩ pull-
down resistors.

Note 7: The specified limits represent the “worst case” value for the parameter. Since these values normally occur at the temperature extremes, additional
noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are cho-
sen to guarantee operation under “worst case” conditions.
