(1) H = High Voltage Level, L = Low
Voltage Level, X = Do Not Care, ↑ = Low to High transition
(2) Shift : Content of each internal register shifts towards serial
output QH. Data at SER is shifted into the first register.

(1) Internal registers refer to the
shift registers inside the device. These values are set by either loading data
from the parallel inputs, or by clocking data in from the serial input.
(2) H = High Voltage Level, L = Low
Voltage Level, X = Do Not Care
