That's right, but they've been part of AD for several years now.

Then there's also the MPQ2222 (Motorola/SGS-Thompson) which is
four 2N2222s in a DIP14, and a couple of exotic but nevertheless
interesting devices:

SSM2100 Log/Anti-Log amp, temperature regulated (Analog Devices)
ICL8049 Anti-Log amp, temperature compensated (Harris)

BTW, what's the difference between the 3046 and the 3086?
Can't seem to recall...
