IC - Powerlink V. 2.3

21.4.15

The 74HCT595 used in this example has an undefined on-position, but

therefor can set the outputs to the tri-state condition via the OutEnable-

Pin 13. If it is more important to have a defined on-position in an applica-

tion, and the OutEnable-pin is not necessary, the 74HCT594 can be used

here.
