NOTES:
4. Transition is measured at ±200mV from steady state voltage with loading specified in AC Test Circuit, V₁ = 1.5V, R₁ = 500Ω
and C₁ = 40pF.
5. To ensure the correct product is entered in the output registers, new data may not be entered into the input registers before the output registers
have been clocked.
6. Refer to AC Test Circuit, with V₁ = 2.4V, R₁ = 500Ω and C₁ = 40pF.
