±1%, CL = 15pF, TA = -40°C to +85°C. Typical values are at VCC = +3.3V, TA = +25°C, unless
otherwise noted.) (Notes 4, 5, 6)

Note 1: Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are 100% tested
at TA = +25°C.
Note 2: Currents into the device are positive, and current out of the device is negative. All voltages are referenced to ground except
VOD.
Note 3: Guaranteed by correlation data.
Note 4: AC parameters are guaranteed by design and characterization.
Note 5: CL includes probe and jig capacitance.
Note 6: Signal generator conditions for dynamic tests: VOL = 0, VOH = 3V, f = 100MHz, 50% duty cycle, RO = 50
, tR ≤ 1ns, tF ≤
1ns (0% to 100%).
Note 7: tSKD1 is the magnitude difference of differential propagation delay. tSKD1 = |tPHLD - tPLHD|.
Note 8: tSKD2 is the magnitude difference of tPHLD or tPLHD of one channel to the tPHLD or tPLHD of another channel on the same
device.
Note 9: tSKD3 is the magnitude difference of any differential propagation delays between devices at the same VCC and within 5°C
of each other.
Note 10: tSKD4 is the magnitude difference of any differential propagation delays between devices operating over the rated supply
and temperature ranges.
Note 11: fMAX signal generator conditions: VOL = 0, VOH = 3V, f = 400MHz, 50% duty cycle, RO = 50
, tR ≤ 1ns, tF ≤ 1ns (0% to
100%). Transmitter output criteria: duty cycle = 45% to 55%, VOD
≥ 250mV.
