Part Number: SN7416
Other Parts Discussed in Thread: SN74ALVCH16973, SN74BCT8244A, SN74BCT8240A, SN74BCT8245A, SN74BCT8373A, SN74BCT8374A, SN74ABT8245, SN74ABT8543, SN74ABT8646, SN74ABT8652, SN74ABT18640, SN74ABT18646, SN74LVT8980, SN74LVT8986, SN74LVT8996, SN74LVTH182502A, SN74LVTH182504A, SN74LVTH18502A, SN74LVTH18504A, SN74LVTH18652A

I need to get a BSDL file for a TI chip: ACH973 53W A2V3 G1, which I believe is a 74ALVCH16973

    Hi,

    We don't have a BSDL file for this chip. That chip is just a buffer (verilog would basically be A = Y a bunch of times).

    Best,

    TI forced me to include a chip number that I don't need info on in order to be able to leave a message about the one that I do need: ALCH16973. I couldn't find that one in the hoops I was forced to jump in order to request info on this one. TI's number for this one is: 74ALVCH16973. There is a JTAG connector on a board that I'm troubleshooting that leads directly to this chip. Sorry for the confusion.

    Hi,

    So the question here is regarding the SN74ALVCH16973? Could you specify exactly what you need from us?

    I'm not familiar with what a BSDL file is in this context, and we don't have BSDL files for any of the devices we offer, including this one. 

    Best,

    The actual part on the board that I'm tasked with troubleshooting is a Ti ACH973, which I believe to be a BGA version of the 74ALVCH16973. It has no leads showing, but it is directly connected to a JTAG connector, so I was hoping to be able to test it via that connector. The traces you see beside the chip are on a daughter board beneath the IC. There are more than 48 traces next to the chip, so they don't match 1:1 to the 16973.

    Hi,

    I'm not convinced that the ACH973 is the ALVCH16973, or that the ACH973 is our part. I cannot find a datasheet for that part anywhere in our internal systems or on the internet. As far as I can tell, we never made the SN74ALVCH16973 in a BGA package either.

    Even if the SN74ALVCH16973 was the correct part number, that part is just a digital buffer/latch as I mentioned before, with no specific JTAG protocol designed into the device. Notice how there are no JTAG ports on the pin mapping in the datasheet. We do have a lot of devices that have some dedicated JTAG functionality built in:

    Note that none of these part numbers end in 973. The first two families (BCT and ABT) work at 5V, and the last family (LVT) works at 3.3V and lower, so that might help you narrow it down if you think it is indeed one of these. The LVT and ABT part numbers also have BSDL files on their product pages. Let me know if this helps you at all.

    Best,
