Input = H or L. The output is in the saturation condition. *2 : The output is ON with MUTE = H and OFF with MUTE = L.MUTE is operable for all channels. With MUTE = L, the output is OFF and the impedance is HI. *3 : 5V supply voltage when the reset output is LOW. *4 : Potential difference of 5V supply voltage between the reset output at LOW and at HI.
