Notes to D.C. characteristics
1. Vref min = 0,5 V, Vref max = 9,5 V, Vc = Vosc = 0 V, I1 at VSS or VDD.
2. See Fig.2.
3. Pin under test at VSS or VDD. All other inputs simultaneously at VSS or VDD.
4. IO = 0, all inputs at VSS or VDD.
5. VOH = VDD 0,5 V, all inputs at VSS or VDD.
6. VOL = 0,4 V, all inputs at VSS or VDD.
7. fBP = 100 Hz, load segment outputs to back-plane output.
C1 C18 0,01 µF, CBP = C1 + C2 + . . . C18 0,05 µF, R1 R18 2 M.
8. Rosc = 0,1 M, Cosc = 390 pF.
9. Number of segments 2 or 18.
For n = 2:
VIO = Vc Vref min --(--V----r--e---f----m----a---x----)---1----8---(---V----r--e---f---m-----i-n----)---- ± VH
For n = 18:
VIO = Vc Vref max + --(--V----r--e---f---m----a---x--)-1----8---(---V----r--e---f---m----i-n---)- ± VH
10. See equation (1).
11. Condition applies with clock oscillator such that fBP = 100 Hz.
