Electrical characteristics
Note 1. When RC oscillation is used, use the external 33 pF capacitor (C).
Note 2. The impedance state is the resistor value of the output voltage.
at VLC3 level output: VO = 0.8 VLC3
at VLC2 level output: VO = 0.8 VLC2
at VLC1 level output: VO = 0.2 VLC2 + VLC1
at VSS level output: VO = 0.2 VLC1
