Help to identify Video Amp IC - 4 channel used for Analogue RGB video buffer
Maybe it was similar to this Maxim chip (that is also capable of some input routing): -



Maxim have a few offerings so if this isn't the part maybe you should pop along to their website for further investigation? Maybe this 14 pin video buffer amplifier (note the standard pin-out as per many op-amp devices - does this ring any bells?): -



There is also the MAX4395 - maybe try this list of potential parts.
