.
Note 2: Current into the device defined as positive. Current out of the device defined as negative.
Note 3: DC parameters production tested at T
A
= +25°C and guaranteed by design and characterization for T
A
= -40°C to +85°C.
Note 4: Current through either output.
Note 5: Guaranteed by design and characterization. Limits set at ±6 sigma.
Note 6: t

Note 7: Measured between outputs of the same device at the signal crossing points for a same-edge transition under the same con-
ditions. Does not apply to loopback mode.
Note 8: Device jitter added to the differential input signal.
