Functional Description
The ’F164A 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 En-
able 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 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 asyn-
chronously, forcing all Q outputs LOW.
