PIN FUNCTIONS

Name

Function

5V Logic Supply.

GND

Logic and Power Ground.

OUT0 to OUT27

DMOS Outputs.

CLAMP

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..

INA, INB, INC, IND

Decoder inputs.

COM1, COM2

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

CHIP ENABLE

A logic high enable the chip.
