I used CD4094 in our application to accomplish the Series Data to parallel output before. Recently we change our design to TLC5917 and got confused with the Timing of the LE signal. So I get 2 questions to be helped:
1. Must the High or Low status of LE signal be detected at positive-going transition of the CLOCK? or no matter CLOCK is exist or not, which like CD4094. According to the Figure11. ( Device Functional Modes - Normal Mode) in the data sheet of TLC5917, it Seems that not need take notice of the clock in transition of the OE and LE
2.in our MicroComputer,we send series data at time that LE goes to High, and then let LE go down to latch the data. And after a few millisecond, OE goes down to Enable the Output, which have a little difference in the sequence of the sending data in Figure 11. Is that have any wrong probably?
