These are used for the video shift registers on Williams games (Defender, Stargate, Robotron etc).

You need 4 for an upright, 8 for a cocktail.

These are the standard power version. It's possible for this fan-out application that the far more common LS might work, but the originals were the non LS. More info on this thread: https://forums.arcade-museum.com/showthread.php?t=150271&highlight=74166

$10 for 4 chips, shipped. Paypal gift.

Each chip will be tested using BK Precision 560 IC tester before shipping.
