Electrical Specifications

NOTE:

VTT supplies the PECI interface. PECI behavior does not affect VTT min/max specifications.

Refer to Table 4 for VTT specifications.

The leakage specification applies to powered devices on the PECI bus.

The input buffers use a Schmitt-triggered input design for improved noise immunity.
