Slew Rate Voltage Ramp rate (dV/dT) 0.5 10 mV/uS 1
di/dt Step current 2 A 2, 3
Notes:
1. Long term reliability cannot be assured in conditions above or below Max/Min functional limits.
2. Step current is done in 100nS
3. di/dt values are for platform testing only. This parameter is not tested on Intel silicon. Testing should go up to and
include IccMax.
