How do I connect a 14-pin ZIF?
The ZIF FFC connector on the listed device is designed to be mated with a 0.5mm pitch Flat Flex Cable (FFC), also known as a flat ribbon connector or ribbon jumper. You could either solder the other end of such a cable to a break-out, or use a similar ZIF connector at the other end, on your own board.



Here is a Digikey search for 14-conductor FFCs compatible with that connector. In case that search link expires, just search DigiKey (or other similar sites) for 0.5mm FFC, the most common manufacturer seems to be Wurth Electronics. 

For a relatively inexpensive breakout, look for SOP28 to DIP28 adapters with 0.5mm pitch on sites like eBay. The 14 solder pads on either half of one of these PCBs will serve as a suitable breakout for the FFC.
