595 Shift Registers

Hey guys!!!

I am experiencing an issue regarding shift registers and its "ability" to randomly (or last shift register state) activate loads.

This issue occurs when I reset the arduino.

If I use an I/O port into the Output Enable pin and at the startup function I'll put that OE pin at 5V can I control this randomness?

Thanks

Well... I found out the solution:

Using a pullup resistor into the OE line and only when that uC port goes down, the outputs are enable.

Thank you so much.
