This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, V_IN and V_OUT should be constrained to the range GND≤(V_IN or
V_OUT)≤V_CC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V_CC). Unused
outputs must be left open.

a. V₁ . . . V_n are the intermodulation or the harmonic frequencies in the 500 Hz to 3400 Hz band.
b. V_OC and V_OR are the individual frequency components of the DTMF signal.
