Y’alls on crack.

I bought some Lite-On led displays with integrated shift register driver a few years back. They’re kinda cool, reducing the microcontroller pin count needed to drive two digits of alphanumeric displays to a mere three — chip select/enable, clock, data in. Not bad at all, even if they don’t have serial out like a proper shift register; the last cell of the shift register is connected to output latch to remove the need to externally fire the latch.

But good luck reading that datasheet.
