Input 4 & Input 5

These input pins control two output channels each when the MODE pin is pulled high.

These pins may be connected to pulse width modulated (PWM) outputs of the control

IC while the MODE pin is high. The states of these pins are ignored during normal

operation (MODE pin low) and override the normal inputs (serial or parallel) when the

MODE

pin is high. These pins have internal active 25

μA pull-downs.

MODE

Mode Select

The MODE pin is connected to the MODE pin of the control IC. This pin has an internal

active 25

μA pull-up.

Serial Input

The Serial Input pin is connected to the SPI Serial Data Output pin of the control IC

from where it receives output command data. This input has an internal active 25

μA

pull-down and requires CMOS logic levels.
