Note:

1. Applies to output buffers

2. This value is for static IDD.

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
