FUNCTIONAL DESCRIPTION
The LS164 is an edge-triggered 8-bit shift register with seri-
al data entry and an output from each of the eight stages. Data
is entered serially through one of two inputs (A or B); either of
these inputs can be used as an active HIGH Enable for data
entry through the other input. An unused input must be tied
HIGH, or both inputs connected together.
Each LOW-to-HIGH transition on the Clock (CP) input shifts
data one place to the right and enters into Q0 the logical AND
of the two data inputs (A
B) that existed before the rising clock
edge. A LOW level on the Master Reset (MR) input overrides
all other inputs and clears the register asynchronously, forcing
all Q outputs LOW.
