Notes to function table for 74F8966
1. H = High voltage level
2. h = High voltage level one setup time prior to the low–to–high LE transition
3. L = Low voltage level
4. l = Low voltage level one setup time prior to the low–to–high LE transition
5. NC= No change
6. X = Don’t care
7. Z = High impedance ”off’ state
8. – = Input not externally driven
9. ↑ = Low–to–high transition
10.↓* = High–to–low transition, latch must be preconditioned before IAREQ
11. H**= Goes to level of pullup voltage.
12.B* = Precaution should be taken to insure B inputs do not float. If they do they are equal to low state.
ABSOLUTE MAXIMUM RATINGS
(Operation beyond the limit set forth in this table may impair the useful life of the device. Unless otherwise noted these limits are over the
operating free air temperature range.)
