Applications
This device is an 8-stage parallel or serialinput/serial-output register having common clock
and parallel/serial control inputs, a single serial
data input, and individual parallel "jam" inputs to
each register stage. Each register stage is a Dtype, master-slave flip-flop in addition to an output
from stage 8. "Q" outputs are also available from
stages 6 and 7. Serial entry is synchronous with
the clock but parallel entry is asynchronous.
In this device, entry is controlled by the
parallel/serial control input. When the
parallel/serial control input is low, data are serially
shifted into the 8-stage register synchronously
with the positive transition of the clock line. When
the parallel/serial control input is high, data are
jammed into the 8-stage register via the parallel
input lines and synchronous with the positive
transition of the clock line. The clock input of the
internal stage is “forced” when asynchronous
parallel entry is made. Register expansion using
multiple packages is permitted.
