Notes:
15. AC characteristics are guaranteed by design and characterization.
16. Skew is the variation of propagation delay between output signals and applies only to output signals on the same
port (An or Bn) and switching with the same polarity (LOW-to-HIGH or HIGH-to-LOW) (see Figure 15). Skew is
guaranteed; not production tested.
