I am having trouble identifying one of the two ICs on my dog's ultrasonic collar tag. The lettering on the 16-pin SOIC package was obscured by some sealant which I had to scrape away, leaving the markings quite faint, so it's possible I'm misreading them (and thus far I have found it impossible to get them to show up at all in a picture).

I can make out a TI logo, and there are three lines of markings which appear to read:

CM060B
49K _G4_  <-- That's an underlined G4
A995

The usual Google technique leads to lots of "In Stock!" and "Register to receive a quote" pages, but no datasheets.

Anyone know what this might be?

EDIT: The second IC on the tag is a quad two-input NAND gate. There is also some sort of crystal or oscillator in a tall, thin metal can (about the dimensions of a resistor but with both leads at the bottom); this appears to be the source of a very steady 40kHz sine wave. See What is this component on my dog's door opening collar? for a wide shot of the PCB with the glue still covering the IC in question.

Is it possible that you scraped off part of the part number printing and that the part is actually like:

...implying a part number CD4060B ?

  • \$\begingroup\$ +1, I'd bet money that this is it: Most likely the CD4060BNSR, CD4060BNSRE4 or CD4060BNSRG4, going by the top side markings listed. "CMOS 14-Stage Ripple-Carry Binary Counter/Divider and Oscillator" \$\endgroup\$ – Anindo Ghosh Jun 20 '13 at 1:25
  • \$\begingroup\$ The M is fairly clear, and doesn't appear to be a D4. I'm still working on getting an image that shows the markings and will post it if I can. \$\endgroup\$ – Kaelin Colclasure Jun 20 '13 at 16:32

    \$\begingroup\$ I have no idea if this is the OP's chip, but +1 for the creativity. That's just awesome. \$\endgroup\$ – DrFriedParts Jun 20 '13 at 17:46

    \$\begingroup\$ Ok, so now I do have an idea ;-) (I called and confirmed -- see my answer for details) \$\endgroup\$ – DrFriedParts Jun 20 '13 at 19:40

It's a TI CD4060

I called my contact at TI.

I can confirm that "CM060B" is the device marking for a CD4060. You can verify independently by calling TI and using service reference 1-1046761093.

Cheers.

  • \$\begingroup\$ Thanks for the definitive follow-up! I was torn over which to mark as the accepted answer, and decided to go with the earlier one. I hope that's okay. Thanks again! \$\endgroup\$ – Kaelin Colclasure Jun 20 '13 at 22:40

    \$\begingroup\$ Yes. Of course that's ok. The other answer is technically wrong, since the marking is actually "CM060B" as you indicated, but I like that answer because its creative. We need more creativity in engineering. \$\endgroup\$ – DrFriedParts Jun 20 '13 at 23:15
