AC ELECTRICAL CHARACTERISTICS
(V
(20% to 80%), f
erwise noted. Typical values are at V
(Notes 1, 5)
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. All voltages are referenced to V
Note 3: DC parameters are production tested at T
Note 4: Outputs are open. Inputs driven high or low.
Note 5: Guaranteed by design and characterization. Limits are set to ±6 sigma.
Note 6: Measured between outputs of the same part at the signal crossing points for a same-edge transition.
Note 7: Device jitter added to the input signal.
