NOTE: a ...h = the level of the steady-state input at inputs A through H, respectively. This data is loaded into the flip-flops while the flip-flop outputs
are isolated from the I/O terminals.
When one or both output-enable inputs are high, the eight I/O terminals are disabled to the high-impedance state; however, sequential operation
or clearing of the register is not affected.
