Characteristics are over recommended operating conditions unless other wise stated.
All of these specifications refer to ST-BUS inputs and outputs with clock source set to CKi.
Typical figures are at 25°C, V
subject to production testing.
Loads on all serial outputs set to 30 pF.
High Impedance is measured by pulling to the appropriate rail with R
