Functional Description
The VHC164 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 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.
