Does anyone have a pinout for the AM26LS34 quad
differential line
receiver chip? It's used in some later Acorn Econet products...
My databooks cover the '30 to '33 only, and a google search didn't
seem
to find a datasheet.
It's the same pinout as a 26LS33, in fact it's almost the same chip,
but with higher input resistance (20K) and higher hysteresis, and it
doesn't have the internal failsafe (output on a 26LS32/33 is guaranteed
to go high if both inputs are unconnected).

THanks. I thought the pinout looked similar (from tracing tracks on the
PCB), but I wanted to check they'd not done anything different with the
enable lines, etc.
Somebody else (sorry, I am terrible with names...) pointed me at a
datasheet, which confirms it's much the same device.
