Hi,
I´m looking for a cheap chip, that allows me to put in its outputs TTL levels 0 or 1, using UART protocol or other.
Basically the chip will latch a value that i send via protocol, until i send the next value.
Does anyone know something like this?
Cheers
It is not at all clear what you want to do.
I don't understand what you mean by "protocol". My understanding of that word is the way a sequence of bytes is arranged, but that does not fit in with what you want to do.
Are you talking about latching just 1 bit or a whole byte?

74HC595...?
What's wrong with using an Arduino pin? That's what Arduinos are for.
"using UART protocol or other"
I vote for other. UART has built in clock that samples the data to decide when to captures highs & lows.
Use shiftout() or SPI.transfer() to provide the clock and do the same into a shift register.
a cheap chip
You can program a 8pdip avr quickly for that.
