NOTES:
5. Controlled by design or process parameters and not directly tested. Characterized upon initial design and after major process and/or design
changes.
6. Transition is measured at
±
200mV from steady state voltage with loading as specified in test load circuit with and C
L
= 40pF.
7. AC Testing is performed as follows: Input levels (CLK Input) 4.0V and 0V, Input levels (all other Inputs) 0V and 3.0V, Timing reference levels
(CLK) = 2.0V, (Others) = 1.5V, Output load per test load circuit and C
L
= 40pF.
8. Applies only when H_BYP = 1 or H_DRATE = 0.
