I have come across a chip that I don't have the pinout of. It's a 4063,
presumably 4000-series CMOS. The one in the device is made by RCA.
It is indeed a 4-bit comparator. Here is the pinout:
1 B3
2 IA<B
3 IA=B
4 IA>B
5 OA>B
6 OA=B
7 OA<B
8 gnd
9 B0
10 A0
11 B1
12 A1
13 A2
14 B2
15 A3
16 Vcc
Good luck,

From the function in the circuit, I would guess
it's some kind of 4 bit
comparator.
Does anybody have the pinouts (16 pin DIL). It's not in any of my CMOS
databooks that I can find. If you do, could you please type them as a
simple text file (as in
