All parameters measured at ƒ ≤ TBDMHz unless noted otherwise.
NOTE 1: Measured from V_DD/2 of the input to V_DDOX/2 of the output.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.
Measured at V_DDOX/2.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 4: Defined as skew between outputs on different devices operating a the same supply voltage and
with equal load conditions. Using the same type of input on each device, the output is measured at V_DDOX/2.
NOTE: 5 Defined as skew within a bank with equal load conditions.
NOTE 6: These parameters are guaranteed by characterization. Not tested in production.
