74HC Datasheet(PDF) – List of Unclassifed Manufacturers

But if the OP is only interested in clocking a subsequent stage, symmetrical output isn’t required. I want to experiment with 74HC chip.

Did you look at the datasheet of the SN74HC? But the larger counter chips that incorporate several like stages do not have access to the divide-by-two stages so you can’t do that.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at I intend to use the 74hc data sheet: The TTL counter is such a beast. Ask a Question Want datasbeet reply to this thread or ask your own question? After that, you can post your question and our members will help you out. Did you derive that from the data sheet? Using a Qd output as the gate input for a frequency counter would be a bad idea! Space Varmint New Member Sep 1, Q0 would be Daatsheet.

Dattasheet Questions Started by norbss Yesterday at Apr 14, 2. BrownOut Banned Sep 1, I don’t know what that other configuration is.

And just because a counter is a synchronous counter doesn’t mean that it’s synchronous in every sense or will be synchronous in cascade. I know the pin datashfet for divide by 4 example 14 to 215 to 32,4,8,12,14 to Ground1 in and 13 out and divide by from a Mr Carlson’s Lab YouTube clip, but I would like to find the pin strappings for the other possibilities I believe I could divide by 2,5,10,20,25,50?

Thread starter Space Varmint Start date Sep 1, Design 74HC dividers. It appears, from looking at the datasheet, that indeed Q4 is a divide by 10 output, when the chip is configured for a decade counter.

Oh, Texas Instruments say it is obsolete do not show its datasheet. And when you want to cascade them, the various stages will be rippled even though within each stage it’s synchronous. You’ll need to choose a username for the site, which only take a couple of moments here.
