8-Bit Parallel In/Serial Output Shift Registers
General Description
This device is an 8-bit serial shift register which shifts data
in the direction of Q
A
toward Q
H
when clocked. Parallel-in
access is made available by eight individual direct data
inputs, which are enabled by a low level at the shift/load
input. These registers also feature gated clock inputs and
complementary outputs from the eighth bit.
Clocking is accomplished through a 2-input NOR gate, per-
mitting one input to be used as a clock-inhibit function.
Holding either of the clock inputs HIGH inhibits clocking,
and holding either clock input LOW with the load input
HIGH enables the other clock input. The clock-inhibit input
should be changed to the high level only while the clock
input is HIGH. Parallel loading is inhibited as long as the
load input is HIGH. Data at the parallel inputs are loaded
directly into the register on a HIGH-to-LOW transition of the
shift/load input, regardless of the logic levels on the clock,
clock inhibit, or serial inputs.
