txb0108 pinout for beginners

by whitechoctaw on Mon Dec 03, 2012 11:31 pm

I have a txb0108 that I want to use with an RPI to interface with a TTL serial device. I have searched the forums and
looked at the dta sheets but I have no confidence in what pins should be used for what. Is there a mapping available
for beginners?

Are you referring to the breakout?: https://www.adafruit.com/products/395
Connect the 3.3v supply from the Pi to VCCA and the TTL Serial supply voltage to VCCB. Connect all the grounds to GND and the rest of the signals connect straight through (a1-B1, A2-B2 etc).
