Functional Description
The 74F164A 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.
Each LOW-to-HIGH transition on the Clock (CP) input
shifts data one place to the right and enters into Q
0
the log-
ical 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.
