8-bit Parallel-out Shift Register

Description

This 8-bit shift register has gated serial inputs and clear. Each register bit is a D-type master/slave flip-

flop. Inputs A & B permit complete control over the incoming data. A low at either or both inputs inhibits

entry of new data and resets the first flip-vlop to the low level at the next clock pulse. A high level on the

input enables the other input which will then determine the state of the first flip-flop. Data at the serial

inputs may be changed while the clock is high or low, but only information meeting the setup and hold time

requirements will be entered. Data is serially shifted in and out of the 8-bit register during the positive

going transition of the clock pulse. Clear is independent of the clock and accomplished by a low level at

the clear input.
