The propagation delay of the Q7 output will depend on the supply voltage and operating temperature range, which you have not specified. In the animation above, the red dot on the upper-left corner is the shift register serial input. Ricardo 4, 14 37 By continuing to use this website, you agree to their use.

There is a potentially better way - actually two ways. Get to Know Us. It seems to me you can clock them as fast as the datasheet allows, it would have nothing to do with the LEDs since I assume you are going to clock in two digits serially ideally so fast the user is not aware of it and then stop so they can be viewed. Not sure I understand what you're saying in the comments above, but it seems le you're confusing clock with the serial input.

Arduino Controlling 74C164 Shift Register

You are commenting using your Twitter account. From then on, if you want to increase the length of the ON section, just shift right as many times as necessary. You need to make sure that the clock period is longer than the sum of the maximum propagation delay of the Q7 output, plus the minimim input setup time of the AB inputs.

Kamil 4, 6 26 You will need to, or you're going to see ghosting.

Here are a few links I found googling about controlling your shift register with PIC: We appreciate your Positive Feedback, and will do the same in return. The LED capacitance shouldn't matter very much provided the resistor value is high enough to allow the swing to easily meet the guaranteed logic levels.

Tie the left input high, and the right input low. Fill in your details below or click an icon to log in: AmazonGlobal Ship Orders Internationally.

Loading recommendations for this item In the image you've shown, disppay are 8 shift registers linked in chain, which let's you input 64 bits and control 8 7-segments displays without the need to multiplex the segments. I know it's not your case, but there's more information on how to drive a similar shift register LS74HC with Arduinos on this answer of mine.
