Terminology again, and probably my fault, let me say that again,
I have 2 lines into the chip, data and clock, data goes to data in on the register, clock goes to the register clock input and then delayed through an r/c into the latch enable input, so the regsister shifts data in, then a few us after the latch is latched, effectively removing the latch section of the chip, its acting like an unlatched shift register, pointless but saves me having to buy parts.
Kinda gives me another idea, I could probably have 2 r/c delays and have a shift register driven by 1 pin, in fact I could have half a dozen daisy chained, cool for driving leds.
