I'm working on project, where we have sn74hc595 shift registers included. Because I got this project without any documentation, it was necessary to understand this connection of shift registers, so I can write code. I am familiar with shift registers, which has separated SRCLK and RCLK in cascade connection. But this kind of connection is the one, I don't understand.
I found some similar problem here: 74HC595 Shift Register Latch Pin, but here is only one shift register.. In datasheet is also mentioned, that SRCLR and RCLK can be connected together: "Both the shift register clock (SRCLK) and storage register clock (RCLK) are positive-edge triggered. If both
clocks are connected together, the shift register always is one clock pulse ahead of the storage register.
If both clocks are connected together, the shift register always is one clock pulse ahead of the storage register. This is ok. Is this also allowed in this kind of connection?
Thanks in advance. If there is any info missing, I will add it.
