Function

5V Logic Supply.

Logic and Power Ground.

DMOS Outputs.

This pin has to be connected to the power supply voltage of the head resistors. Each of the

output DMOS have their drain connected with the anode of a protection diode, all the cathodes

of the protection diodes are connected to the clamp pin. In order to have the device supplied,

the CLAMP pin needs to be connected to the power..

Decoder inputs.

A low logic input on these pins enables the outputs selected by the decoder inputs.

A logic high enable the chip.
