Note 5: The 16 switches operate independently.
Note 6: Serial data is clocked in on the rising edge of CLK.
Note 7: The switches go to a state retaining their present condition on the rising edge of LE. When LE is low, the shift register data
flows through the latch.
Note 8: DOUT is high when switch 15 is on.
Note 9: Shift register clocking has no effect on the switch states if LE is high.
Note 10: The CLR input overrides all other inputs.
