Notes:
1. The eight switches operate independently.
2. Serial data is clocked in on the L → H transition CLK.
www.DataSheet4U.com
3. The clear input over rides all other inputs.
4. 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.
5. is high when switch 7 is on.
6. Shift register clocking has no effect on the switch states if LE is H.
