Functional Description
The HD74AC164/HD74ACT164 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 inputs. An unused input
must be tied High.
Each Low-to-High transition on the Clock (CP) input shifts data one place to the right and enters into Q
0
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.
