How to convert signals from a raspberry pi to a relay board.

Joson asked Jul 10,2020

How to use an TXS0108E bi-directional logic shifter to convert 3.3V signals from a raspberry pi to a 5.0V signal to a relay board. 

I'm trying to trigger a 5 volt relay board using a raspberry pi. Basically on the a-side I have my 3.3 raspberry pi connections. And on the b-side I have my 5-volt connections but this doesn't work. I've even checked with a multimeter and I'm getting millivolts. so I'm clearly doing something wrong. Any help would be appreciated.
