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 are production tested at +25°C. DC limits are guaranteed by design and characterization over the full oper-
Note 4: Guaranteed by design and characterization. Limits are set to ±6 sigma.
Note 5: Measured between outputs of the same part at the signal crossing points for a same-edge transition.
Note 6: Device jitter added to the input signal.
