Note *1 : Voltage across both ends of 8

Ω load inserted between outputs. 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.
