INPUTS
A, B, C, D, E, F, G, H (Pins 11, 12, 13, 14, 3, 4, 5, 6)
asynchronously entered in parallel into the internal
flip−flops when the Serial Shift/Parallel Load input is low.
SA (Pin 10)
input is high, data on this pin is serially entered into the first
stage of the shift register with the rising edge of the Clock.

Either may be used as an active−high clock inhibit.
However, to avoid double clocking, the inhibit input should
go high only while the clock input is high.
