Notes
1. This pin has an on-chip 1.0M
pullup resistor.
2. An a.c. coupled sine or squarewave.
3. See Table 1, Tone Decode Frequencies.
4. Delay between the change of input (Tone/N
OTONE
) and the change at the Q0 - Q3 outputs.
5. The signal input maximum value is determined by the formula V
DD
/2.83.
