Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings 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. NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51-7.

NOTES: A. CL includes probe and test-fixture capacitance. B. Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following characteristics: PRR 1 MHz, ZO = 50 , tr = 6 ns, tf = 6 ns. C. The outputs are measured one at a time with one input transition per measurement. D. tPLH and tPHL are the same as tpd.
