Notes:
1. VREFac is equal to VREFdc plus noise.
2. VIH max and VIL min apply for pulse widths less than one-quarter of the cycle time.
3. Input rise and fall times must be a minimum of 1V/ns, and within 10% of each other.
4. Applies to: CK, CK, KD, KD, SA, R, W, D.
5. Applies to: RST, MVQ, MZT, PZT.
