Transistors in DIP?

Not sure what series this is

- NPN or PNP bipolar
or
- FETs

small-signal transistors in through-hole DIP package.

Where should I start looking?

The only one I know off off-hand is the MPQ2222, a quad array of
2N2222-type NPN transistors.

This part appears to be obsolete. You might find a few at surplus
dealers, or at the big $100-minimum-order IC consolidators. Blue Star
seems to have a couple of dozen in stock at $2 each (ouch!)

If you're thinking of going into production with parts like this, I
think you'll probably decide to redesign using more modern
surface-mount arrays. There seems to be little demand for DIP-type
arrays any more, and parts cost and availability are likely to become
an even worse problem in the future.

If you only need a handful, search around, or just make your own using
DIP headers and discretes.

Common parts meeting your very vague outlines:

ULN2003A = 7 darlington-connected NPN pairs, all the emitters common.

CA3046 = 5 NPN's, pretty well matched, 2 of them connected as a
differential pair

CD4007 = 3 pairs of N and P channel transistors, one hooked up like an
unuffered CMOS inverter, the other two pairs with independent drains
and sources

At one point there also existed arrays of 4 2N2222's or 4 2N3906's
etc. in a DIP but I haven't seen these in years. In fact the CA3046 I
mention above isn't very common anymore either.

I suggest forgetting it. There's very little like that. There was stuff like the
CA3086.

Wow, it seems Intersil still have it.

transistor arrays.
They come in many forms.

ULN2002A are open collector types good for 50volts at a .5 amps.

You should try it. :)

Seems to me I saw a whole lot of stuff that used the 3046 and 3086 over the
years.
