Notes:
1. All other pins not under test = 0 V.
2. DQ, LDQS, LDQS , UDQS, UDQS are disabled and ODT is turned off.
3. The VDDQ of the device under test is referenced.
4. VDDQ = 1.7 V; VOUT = 1.42 V. (VOUT - VDDQ)/IOH
must be less than 21 Ω for values of VOUT between VDDQ and VDDQ -
0.28V.
5. VDDQ = 1.7 V; VOUT = 0.28V. VOUT/IOL
must be less than 21 Ω for values of VOUT between 0 V and 0.28V.
6. The values of IOH(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 VIHmin plus a noise margin and VILmax minus a noise margin are delivered to an SSTL_18 receiver.
