The logic on-off function allows the user to shut off the converter’s output using a simple TTL logic signal or mechanical switch, and avoids having to turn off the DC input bus. This feature is ...

The 74HC00 data sheet warns that inputs must not be allowed to float because this makes the output indeterminate. Now, that in itself is a good reason, but there is more… In my previous column, we ...

Somehow, though, that doesn’t seem as much fun as virtually connecting 7400 chips together. Don’t ask us why. There’s also a link to an impressive open source web-based logic simulator. You can grab ...

Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in terms ...

EPC has announced a laser driver that integrates a 40V 10A GaN power switch with a differential input gate driver. Called EPC21603, its inputs are LVDS (low-voltage differential signalling) compatible ...
