Notes: 1. Impedance measurement condition for output source DC current: VDDQ = 1.7V; VOUT = 1420mV;
(VOUT
VDDQ)/IOH must be less than 23.4
for values of VOUT between VDDQ and VDDQ
280mV.
Impedance measurement condition for output sink DC current: VDDQ = 1.7V; VOUT = 280mV;
VOUT/IOL must be less than 23.4
for values of VOUT between 0V and 280mV.
2. Mismatch is absolute value between pull up and pull down, both are measured at same temperature and
voltage.
3. Slew rate measured from VIL(AC) to VIH(AC).
4. The absolute value of the slew rate as measured from DC to DC is equal to or greater than the slew rate
as measured from AC to AC. This is guaranteed by design and characterization.
