AC Electrical Characteristics
Over recommended operating supply and temperature ranges unless otherwise specified. (Note 3)
Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device
should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
Note 2: Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except V
V
Note 3: All typical are given for V
Note 4: Output short circuit current (I
Note 5: The parameters are guaranteed by design. The limits are based on statistical analysis of the device performance over the PVT (process, voltage and
temperature) range.
Note 6: t

Note 8: t

Note 9: The parameters are guaranteed by design. The limits are based on statistical analysis of the device performance over the PVT range with the following test
equipment setup: Agilent 86130A used as stimulus, 5 feet of RG142B cable with DUT test board and Agilent 86100A (digital scope mainframe) with Agilent 86122A
(20GHz scope module). Data input jitter pk to pk = 22 picoseconds; Clock input jitter = 24 picoseconds; t
picoseconds.
Note 10: Propagation delay, rise and fall times are guaranteed by design and characterization to 200MHz. Generator for these tests: 50MHz ≤ f ≤ 200MHz, Zo =
50Ω, tr, tf ≤ 0.5ns. Generator used was HP8130A (300MHz capability).
Note 11: f
is guaranteed by design and characterization. A minimum is specified, which means that the device will operate to specified conditions from DC to the minimum
guaranteed AC frequency. The typical value is always greater than the minimum guarantee.
