Table 19-3. Operating Range for CYNSE70032
20.0
Table 20-1 shows the AC timing parameters for the CYNSE70032 device; Table 20-2 shows the same parameters but for 2.5V.
Figure 20-1 shows the device’s input wave form, and Figure 20-2 and Figure 20-3 show the device’s output load. Figure 20-4
shows a timing waveform diagram.

Notes:
12. Based on an AC load of CL = 30 pF (see Figure 20-1, Figure 20-2, and Figure 20-3).
13. These parameters are sampled but not 100% tested, and are based on an AC load of 5 pF.
11. Values are based on 50% signal levels.
