You're probably right, Kai, in that the NXP datasheet

http://www.standardics.nxp.com/products/...f4094b.pdf

isn't particularly good. That block diagram, Figure 1, however, provides all the information that's needed, aside from the clock sense, and one is usually safe in assuming clock inputs, not otherwise designated, to be positive-going. However, that's covered in the paragraphs right on the first page,

The HEF4094B is an 8-stage serial shift register. It has a storage latch associated with
each stage for strobing data from the serial input to parallel buffered 3-state outputs
QP0 to QP7. The parallel outputs may be connected directly to common bus lines. Data is
shifted on positive-going clock transitions. The data in each shift register stage is
transferred to the storage register when the strobe (STR) input is HIGH. Data in the
storage register appears at the outputs whenever the output enable (OE) signal is HIGH.

Two serial outputs (QS1 and QS2) are available for cascading a number of HEF4094B
devices. Serial data is available at QS1 on positive-going clock edges to allow high-speed
operation in cascaded systems with a fast clock rise time. The same serial data is
available at QS2 on the next negative going clock edge. This is used for cascading
HEF4094B devices when the clock has a slow rise time.
 

should be more than enough.

I wasn't looking at any datasheet when I made my comment, but, rather was recalling the days when one used such parts form RCA, Motorola, NSC, and Fairchild.

A much better choice, in my opinion, particularly in working with 5-volt MCU's, is the 74HC595, if only for its improved output current, but that's just my opinion.

I understand that there's a language barrier. However, I'll bet you didn't learn your English in school, Kai. I'd guess that your understanding of English came from your desire to understand the datasheets, most of which are printed in English. Spoon-feeding him the information won't help the O/P learn what he needs to learn, nor will it make the language barrier go away.

In general, as you know, I disapprove of spoon-feeding information to folks who are fundamentally unwilling to do the underlying work, at least to the extent of seeking out and finding the fundamentals of what they say they want to do. Nobody learns as much from having someone guide them through their assignments as they would from actually performing the work themselves, and that includes the basic research.

I'm still curious how he's planning to use this very, Very, VERY weak-output part to do anything useful without lots of "help". Try not to forget the other thread he's opened. He's not just trying to learn circuit design ... He's trying out his skills at getting someone else to do his thinking and other work for him.
