NOTES:
1. The Address to Enable setup time is the time before the High-to-Low Enable transition that the Address must be stable so that the correct
latch is addressed and the other latches are not affected.
2. The Address to Enable hold time is the time before the Low-to-High Enable transition that the Address must be stable so that the correct
latch is addressed and the other latches are not affected.
