Step 9Soldering the components - 7
I tidied up the data lines from the chip to the surge suppressors via resistors.
The texas instruments datasheet says the chip needs 27 ohm resistors in series with all its data lines - all ten of them (eight downstream, two upstream). I could find only 22 ohm resistors in the various junked boards I could collect, so they would have to do.
The pads of the chip were tinned in preparation of soldering it in position.
