DC SPECIFICATIONS (2.3V < VCC < 2.7V unless otherwise specified)
DYNAMIC SWITCHING CHARACTERISTICS (Ta = 25°C, Input tr =tf = 2.0ns, CL = 30pF, RL = 500Ω)
1) Number of outputs defined as "n". Measured with "n-1" outputs switching from HIGH to LOW or LOW to HIGH. The remaining output is
measured in the LOW state.
2) Number of outputs defined as "n". Measured with "n-1" outputs switching from HIGH to LOW or LOW to HIGH. The remaining output is
measured in the HIGH state.
3) Parameters guaranteed by design.
