Notes:
1. All other pins not under test = 0 V.
2. DQ, LDQS, LDQS , UDQS, UDQS are disabled and ODT is turned off.
3. V DDQ = 1.7 V; V OUT = 1.42 V. (V OUT - V DDQ )/I OH must be less than 21 ? for values of V OUT between V DDQ and V DDQ -
0.28V.
4. V DDQ = 1.7 V; V OUT = 0.28V. V OUT /I OL must be less than 21 ? for values of V OUT between 0 V and 0.28V.
5. The values of I OH(dc) and IOL(dc) are based on the conditions given in Notes 3 and 4. They are used to test drive current
capability to ensure V IH min plus a noise margin and V IL max minus a noise margin are delivered to an SSTL_18 receiver.
