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
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 S
0
and S
1
, which are internally decoded to select
either 鈥減arallel entry鈥? 鈥渉old鈥? 鈥渟hift left鈥?or 鈥渟hift right鈥?as
described in the Truth Table. All inputs have 50 k

pull-
down resistors.
