Notes:
1. The eight switches operate independently.
2. Serial data is clocked in on the L→H transition CLK.
3. The switches go to a state retaining their present condition at the rising edge of LE. When LE is low the shift register data flows through the
latch.
4. DOUT is high when data in the shift register 7 is high.
5. Shift register clocking has no effect on the switch states if LE is H.
6. The clear input overrides all other inputs.
