Below is an animation of how one shift register works thanks to totymedli for the great animated gif. Feedback is very important to us. Therefore, the data sheet did not provide enough information to answer your question. Amazon Renewed Refurbished products with a warranty. You will need to, or you’re going to see ghosting. It might seem like it should be possible to shift the LED data so fast that the data being shifted through won’t be visible, but LEDs are remarkably fast.

This delay will also depend on the loading of the resistor and LED connected to Q7. See questions and answers. We ship your orders within business days after the payment cleared. Get to Know Us. Imagine now that this overflow bit is fed into a 2nd shift register serial input. Suggest using 74HC parts ped have a built-in latch- that way you won’t have ‘ghosting’. I know that LEDs have some capacitance. All products are quality dieplay. Naturally, 74hc1164 should use the worst-case numbers, or a bit lower, such as 10MHz, to account for unknowns, but the 1.
To realise this, we connect the Q7 pin from the first 74HC with the data input of the second 74HC There is a potentially better way – actually two ways.

You will need to, or you’re going to 74h1c64 ghosting. A shift register like the one you mentioned will take 8 bits sequentially one at a time and output them in parallel on its 8 outputs.

I was looking for some ideas and I found this 7-segment LED driver:.
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 ped clock in two digits serially ideally so fast the user is not aware of it and then stop so they can be viewed.
