2. Serial data is clocked in on the L to H transition of the 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 flow through the latch.
4. D
OUT
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 high.
6. The CLR clear input overrides all other inputs.
