Thanks in advance!

Cannot find this part# in any of the HP cross references that I have. All the similar part #s are for linear ICs.

Sorry I cannot help.

I checked all of the HP xref files I could find. I went through them page by page rather than take the chance that the pdf file search would miss them. Some of the scans are pretty rough.

I also checked for an NSN to see if there were alternative part numbers, but no luck. It appears that it was an HP only part that wasn't a normal off the shelf item.

I was hoping that it was an off the shelf item that was "selected". There's a lot of information available for
Tektronix items like this, but not HP.  :-[

I appreciate you checking though, many thanks!

I hate to admit it, but it never occured to me to check ECG/NTE, thanks! I guess that I've slowed down as I gotten  older.

You've got me in the ball park now though!

A pair of the 1826-0570 chips are used in the inputs of the HP 5335A counters and are pretty much non-existant in the spare parts department.

The chips are fine in the pair of 5335A's that I have, but I wanted to head off possible problems in the future. I'd hate to have to scrap one somewhere down the line because of a two dollar IC that I can't find a replacement for.

They are only 200Mhz counters. They max out somewhere around 270Mhz or so with 100uv input if I remember right. I can't help but wonder if the NTE919 would work in this application though. The datasheet lists a response time of only 80ns.

Unless I'm missing something, that doesn't seem any where near fast enough handle triggering.

thanks again,
WoD
