Note:
1. Applies to output buffers
2. This value is for static I_DD.
3. Applies to input and bi-directional buffers with hystersis
4. Test condition = CMOS compatible
5. 3-state or open-drain output must be in the high-impedance mode.
6. Specifications only apply with pullup terminator turned off.
7. Specifications only apply with pulldown terminator turned off
