5-7 digit up/down counter with display

by Sam Goldwasser <sam@[EMAIL PROTECTED] > Jun 22, 2008 at 08:32 PM

I know, not really repair, but this newsgroup has at least as good
suggestions as the others and I'll cross-post to sci.electronics.misc.

I need to either build or acquire an up/down counter with LED display
that is at least 5 digits, 7 preferred.  Count speed is 10 MHz max.

I found the Maxim ICM7217
 (http://datasheets.maxim-ic.com/en/ds/ICM7217-ICM7217C.pdf)

which seems easy enough to use - 2 of these and a bunch of 7 segment LED
displays.  But I'm open to other suggestions.

Even if someone had a complete unit scrapped out they'd be willing to
sell cheap! :)

Thanks.
