In the video "74HC595 & 74HC165 Shift Registers with Arduino" at about the 14 minute mark there is a reference to a resistor array. Any chance you can share with us the name and data sheet for this particular resistor array? Thanks
Here is a PDF of the datasheet for the Bourns series of resistor arrays similar, or maybe the same as, the ones in the video.
I get mine from DigiKey.
