I've come across a few old ICs and haven't been able to find out much
about them - lots of places on the 'net are willing to sell them but I
couldn't find a data sheet - only one clue that they _might_ be dual
op-amps. They are small cans (TO-??) with eight leads protruding from
the bottom, marked SG 1458T with a 1976 date code. Any help identifying
them would be appreciated. Kind of hoping they're really some sort of
shift register ...
Alas I think they're just plain 1458 dual op-amps. A very common device
(probably more common in an 8 pin DIP).
