Notes
1. Assumes use of external components as shown in the application diagram; see Fig.38.
2. R_L = 10 kΩ.
3. R_L = 1 kΩ.
4. The typical value is as follows: ^{1----.--6V---5--}_D---^×_D----_A-3---.--3-
5. The typical value is as follows: ^{2----.-V-5---}_D-^×---_D--3-_A---.-3--
6. Pull-up/down devices are protected by a pass-gate and do not behave as a normal resistor for external applications
7. Pull-up/down resistors are connected to external power supply (V_DDE/GND).
8. Minimum condition for V_i = 4.5 V, maximum condition for V_i = 5.5 V.
9. Accounts for 100 mV voltage drop in both supply lines.
10. Minimum condition for V_TOL = 4.5 V, maximum condition for V_TOL = 5.5 V.
11. Leakage path from pad to ground.
