Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are
observed.

TEST CIRCUIT AND WAVEFORMS
Notes: 1. CL includes probe and jig capacitance.
2. All input pulses are supplied by generators having the following characteristics:
PRR≤1MHZ, ZO=50Ω, tr≤2.5ns,tf≤2.5ns.
3. The outputs are measured one at a time with one input transition per measurement.
