SN74ALVCH16373: EOL issue of ZRDR package

Lee, Sam

Part Number: SN74ALVCH16373

Hi team,

It seems that SN74ALVCH163ZRDR is not sold and it's been replaced by 74ALVCH163ZRDR.

Are both devices equal on package, pin layout and performance, ot not?

Thanks.

    Hi Sam,

    Are you looking for a 74ALVCH163ZRDR or a 74ALVCH16373ZRDR?  One of those exists and is orderable in our store, the other does not exist and never did from what I can find.

    I see the 74ALVCH16373ZRDR as being available to order/ship and having millions of units stocked. Here is a link to the TI store page for that device.

    Also, do you have a datasheet for the 74ALVCHxxxx device you are looking for?  It would help me figure this out.

    Hi Maier,

    Sorry for typo. It's 74ALVCH16373ZRDR.

    A customer used SNALVCH16373ZRDR in old times, but it's not available now. Instead, the store has 74ALVCH16373ZRDR. Are these same? T The two datasheets are exactly same as sces020i.pdf (16-BIT TRANSPARENT D-TYPE LATCH WITH 3-STATE OUTPUTS--SN74ALVCH16373 (Rev. I) ) in our ESP.

    Thanks.

    These two should be identical - I'm not sure what the difference is, but I would guess it was either an acquisition or a name change for a customer. In logic, the function, 16373 in this case, typically denotes both how the part works and the pinout, and the family, LVCH, indicates the electrical specs/features. The SN and 74 basically have no meaning besides indicating that this is a TI part.
