Note 1: Measurements are made with the device in thermal equilibrium.
Note 2: Current into a pin is defined as positive. Current out of a pin is defined as negative.
Note 3: DC parameters production tested at T
A
= +25°C and guaranteed by design over the full operating temperature range.
Note 4: Single-ended input operation using V
BB
is limited to (V
CC
- V
EE
) = 3.0V to 3.8V.
Note 5: Use V
BB
only for inputs that are on the same device as the V
BB
reference.
Note 6: All pins open except V
CC
and V
EE
.
Note 7: Guaranteed by design and characterization. Limits are set at ±6 sigma.
Note 8: Measured from the 50% point of the input signal with the 50% point equal to V
BB
, to the 50% point of the output signal.
Note 9: Measured between outputs of the same part at the signal crossing points for a same-edge transition. Differential input signal.
Note 10: Measured between outputs of different parts under identical condition for same-edge transition.
Note 11: Device jitter added to the input signal. Differential input signal.
