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 MΩ.

8. Rosc = 0,1 MΩ, Cosc = 390 pF.

9. Number of segments 2 or 18.

For n = 2:

For n = 18:

10. See equation (1).

11. Condition applies with clock oscillator such that fBP = 100 Hz.
