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.
From the function in the circuit, I would guess
it's some kind of 4 bit
comparator.
Correct, RCA data book lists as CD4063B CMOS 4-Bit Magitude 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
Here's the pinout:
1 : B3
2 : (A<B)in
3 : (A=B)in
4 : (A>B)in
5 : (A>B)out
6 : (A=B)out
7 : (A<B)out
8 : Vss (or Gnd)
9 : B0
10 : A0
11 : B1
12 : A1
13 : A2
14 : B2
15 : A3
16 : Vdd
