I am working on a video level translator ( analog to TTL) It has a 5 pin SOC IC that has "A14" on it. Pins are GND, +5, Analog in, output and the other not used.

Any help would be appreciated.

I've never come across any function like this. What sort of TTL signal can
you 'translate' what is essentially a multi-level analogue signal into ?

Computer monitor / character generator stuff.

Look up Analogue to Data converters and see if anything pops up for you.

Looking to convert video from a camera or TV to a data stream? There are
any number of devices that do that, most need support stuff though.

It could be a CGA to EGA adapter. The EGA standard used two TTL-like signals per color to send 4 levels of brightness from the PC videocard to the monitor.
