INPUTS
A1, A2 (Pins 1, 2)
to be entered into the first stage of the shift register. For a
high level to be entered into the shift register, both A1 and
A2 inputs must be high, thereby allowing one input to be
used as a data−enable input. When only one serial input is
used, the other must be connected to V
