There are a couple of other sites out there for data sheets,  besides the 
mfrs.  Try Dial Electronics in the UK for one example.  And then you could 
always do like I used to do,  look up a substitute (I have an ECG book handy 
but I understand they got bought out by NTE?) And see if that'll give you any 
useful info.
