SWITCHING CHARACTERISTICS over INDUSTRIAL operating ranges (Note 2)
(continued)
Notes:
1. These parameters are not 100% tested, but are evaluated at initial characterization and at any time the design is modified
2. See Switching Test Circuit for test conditions. Switching waveforms illustrate true clocks only. Switching waveforms can be
3. Parameters measured with 16 outputs switching.
