c VOX output pin. Open collector output.

c Chip enable input pin.

c Data input pin.

c Clock input pin.

c Reset pin. Power-on reset.

c Pad control pin. By connecting this pin to

GND or to S. VCC (pin 63) through a resistor,

it is possible to use the line current for gain

control and to control the operating current

for BN switching.
