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 ?
