Boolean Function Generator

A two chip boolean function generator.


This is a boolean function generator utilizing a SN74150N 16-to-1 multiplexer I got from a scrap metal lot on ebay. Using the DIP switches, any 16 bit serial signal can be generated. This is very useful when it comes to testing UARTs as it much more compact than carrying around a palmtop computer and my TTL to RS232 Adapter.
