(pre-Columbian) data book. IIRC Intel really
didn't make any of its TTL
parts, as their fab was dedicated to PMOS, NMOS, and later, CMOS devices.
Therefore I'd suspect that the i8205 (and also the i3205) were strictly TTL,
or, more correctly, schottky TTL. The i8205, by the way, sinks only 10 mA
as opposed to the schottky equivalent, the 'S138, which sinks somewhere
between 16 and 24 mA, depending on whose databook of that day you consult.
This was probably more specsmanship than technology, however.
My intel data book set for the 1974-1981 window is fairly complete and the
I8205 has the exact same specs ans the TI LS138. Intel did have bipolar
fab back then and parts they did there included things like 3212, 300x,
8216/8126, 8224, 8228/38, an assortment of Bipolar PROMs and later part
like 8282, 8283, 8219, 8284, 8284A and others. Their capability is limted
so they did farm out stuff (under license) to TI and AMD.
