FUNCTIONAL DESCRIPTION
The LS164 is an edge-triggered 8-bit shift register with
serial 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 (AB) 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.
