74HC126D buffer IC with Arduino Uno 3

I want to connect 74HC126D buffer IC with Uno 3. How I can connect it ? which pins to connect with which pins on uno 3 :roll_eyes:

What do you want to do with it?

You simply connect one of the inputs, that is pins 2, 5, 9 or 12 to the arduino output pin of your choice. Then pin 1, 2, 10 or 13 controls if the output is in a high impedance tri state mode, low for tri state, high for active. Then connect the output pin 3, 6, 8 or 11 to what ever you want to drive.

Thanks. I want to hack a dc servo motor which has 74hc126d. I want to make my own with arduino uno. I also want to connect optocoupler moc7811. Can you please tell me how to connect 4 pins of position encoder ? I posted in sensors thread but no reply. :fearful:

I also want to connect optocoupler moc7811.

Te MOC7811 is not an opto coupler it is an opto slot.
Use it like this (attached)

Can you please tell me how to connect 4 pins of position encoder

What position encoder, there are lots of different types.

I want to connect AS5145 Encoder to uno 3. Which pins to connect ?

See:- http://code.google.com/p/libas/

Sorry to say but there is nothing to read or download on http://code.google.com/p/libas/

:(

I'll tell you what you google arduino AS5145

I already done that. It goes to arduino italiano forum. I used translater. Its not about pin connections. I only want to know which pins of as5145 goes where in uno 3. XD
