DC Electrical Characteristics and Operating Conditions
Note 1 applies to the entire table; Unless otherwise noted: +0°C ≤ T
Notes:
Stresses greater than those listed in Table 5 may cause permanent damage to the device.
This is a stress rating only, and functional operation of the device at these or any other
conditions outside those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended periods may
affect reliability.
1. All voltages referenced to Vss (GND).
2. Overshoot: Vih(AC) ≤ Vdd + 0.7V for t ≤
3. Vddq can be set to a nominal 1.5V ± 0.1V or 1.8V ± 0.1V supply.
4. Typically the value of Vref is expected to be 0.5 x Vddq of the transmitting device. Vref is
5. Peak-to-peak AC noise on Vref must not exceed ±2% Vref(DC).
6. Vref is expected to equal Vddq/2 of the transmitting device and to track variations in the DC
ing normal operation, Vddq must not exceed Vdd. Control input signals may not have pulse
widths less than

level of the same. Peak-to-peak noise (non-common mode) on Vref may not exceed ±2% of
the DC value. Thus, from Vddq/2, Vref is allowed ±2% Vddq/2 for DC error and an addi-
tional ±2% Vddq/2 for AC noise. This measurement is to be taken at the nearest Vref bypass
capacitor.
