I can't find it in a databook, but I've found a circuit that uses it --
the 'Head Amplifier Playback' module (board P50) in a Philips VR2020 VCR
[1].It seems to contain 8 NPN transistors and nothing else (at least the
schematic of that board shows the internals of the IC as 8 transistors
only) and consists of 2 identical sections.
That's brilliant, thanks. I assumed that whatever was going on in there
was coupled somehow, so treating it as two seperate arrays should make
understanding easier as you say, as well as making the schematic a
little clearer :)
cheers
