These are stress rating only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. The maximum package power dissipation is calculated using a junction temperature of 150C and a board trace length of 750 mils. INTERNATIONAL MICROCIRCUITS, INC. 525 LOS COCHES ST.

The specifications for parameters in this table are applicable only after any appropriate stabilization time as elapsed. Ref Duty Cycle must be 50% +/- 5%. Time required for the integrated PLL circuit to obtain phase lock of its feed back signal to its reference signal. For phase lock to be obtained, a fixed-frequency, fixed-phase reference signal must be present at CLK. Until phase lock is obtained, the specifications for propagation delay, skew, and jitter parameters given in the switching characteristics table are not applicable. Uses the averaging feature of the scope to remove the jitter component. The test load is 30pF//500. TR/TF are measured at 0.4V to 2.0V. INTERNATIONAL MICROCIRCUITS, INC. 525 LOS COCHES ST.
