Sorry about the late response. You can learn more about this open source robotics computer and its BeagleBone predecessors here. In each of the multiplexers data is routed from a particular input to the output. How datasneet of this do you understand?

Macro code Logic function No. You cannot use a pot of that kind to drop power.

No, create an account now. Firstly, you have to begin with basic digital logic and boolean algebra. I must have been very tired when I tried to throw this project together. I get that high and low refer to the voltage, but I feel I am missing something. Unless I am completely wrong in dafasheet understanding.

Do you already have an account? BeagleBone Blue for Robotics Applications: Try Findchips PRO for data datashedt SiDU Jul data sheet 8 of 1 datasheet S Ya that was a face palm moment.


Discussion in ‘ General Electronics Chat ‘ started by atrumbloodMay 13, For your reference I have included a link to the datasheet.

Devices U5 and U8 were added datashet cursor control.

I’m in trouble now. The led on the far left top of the photo is just there to show that the power is on. The device can provide any logic function of four variables and its negation with correct manipulation.

G with a line over the G.

May 13, 2. May 14, 7. This is called a 3-bit binary coded decimal. Y will follow the selected datashedt only when G’ is LOW. My power supply was not exactly 5 volts it was more like 12V! May 13, 5. What is the purpose of that potentiometer? Actually this chip on page 4 lists a zero as 0. Philips Semiconductors reserves the right to change the specification in any datashest without notice.


Sorry, I’ll stick to the facts next time. There are only 10 types of people in the world, those who understand binary and those who don’t. In other words becomes ? Dataeheet am here in hopes that I can gain some better understanding on how to use multiplexors.
