1.4 Pin definitions and functions

Pin No. Symbol Function

1,18,19,

GND Ground; to reduce thermal resistance place cooling areas on

PCB close to these pins. The GND pins are connected internally

to the heat slug at the bottom.

2CLKSPI Interface Clock input; clocks the shift register; CLK has an

internal active pull down and requires CMOS logic level

inputs;see also chapter SPI

3CS

SPI Interface chip select input; CS is an active low input; serial

communication is enabled by pulling the CS

terminal low; CS

input should only be switched when CLK is low; CS

has an

internal active pull up and requires CMOS logic level inputs ;see

also chapter SPI

4DI SPI Interface Data input; receives serial data from the control

device; serial data transmitted to DI is a 16 bit control word with

the Least Significant Bit (LSB) being transferred first; the input

has an active pull down and requires CMOS logic level inputs; DI

will accept data on the falling edge of CLK-signal; see also

chapter SPI

5DOSPI Interface Data output; this tristate output transfers

diagnosis data to the controlling device; the output will remain 3-

stated unless the device is selected by a low on Chip-Select CS
