Looking for a Active “LOW” Tri-state Buffer

Support Q&A
1

I am looking for a Active “LOW” Tri-state Buffer similar to a TC7SZ125F but with the input enabled on LOW.

Can anybody suggest a part number?

Thank you!

I got it. 74LVC1G125GV seems to be doing what I need.

My question now becomes : what is the filter I need to use in DigiKey search to filter out the parts with this characteristic?

I believe most tri-state buffers are /OE which means output enabled on low.

There is no parametric search for this feature, this is checking datasheets for function tables to verify:

Thank you. that is what I did.

That brings another question. :slight_smile:

Why are there no parameters to search for this feature?

I think the reason is most buffers would have an active low output enable.

Because maintaining a parametric dataset for millions of parts is difficult and costly. Lines need to be drawn somewhere…

Also, discrete logic devices of the type are fairly well standardized. One might consult a list of device functions to identify an item of interest.
