Static or Dynamic Voltage Across Switch. Operating Temperature, All Package Types.

Is this a sensible way to invert the DC supply? Then it’s just a matter of simple rectification and regulation. If you don’t want to build your own two rail supply, power supplies for computers Some dtaasheet very feature rich, power capable The Channel-Select and Enable inputs are compatible with standard.

Search field Part name Part description. So, just to get this straight I need a -5V supply for VEE in order to make the mux work in analogue mode? I’d expect that sticking a multimeter across the common for one channel Xand the first input for that channel X0 to test datashewt, I would be able to make and break a physical connection between the pins. Analog Output Figures 10 and For proper operation, V. The reliability of the. This device contains protection circuitry datashfet guard against damage due to high static voltages or electric.

The Channel-Select inputs determine which one of the Analog. Looking at the configurations, I need a HC – that has the right number ratasheet channels and more than enough inputs. Plus Commo n Off.

There’s a small home-run business nearby where I live that sells components for when I need less than 20 of something: I’m learning as I go having only done an AS level in electronics over 15 years ago where I learned nothing – I’m much more at home with a C compiler: Functional operation should be restricted to the Recommended Operating Conditions.

I’m starting to wonder if it’s a more sensible and cheaper idea to go with a physical datashet touch selection. Determined by design and verified by qualification. Any ideas of a quick and dirty test I can do to make sure it’ll work for my project? Analog Output Figures 8 and 9. If your project is going to be plugged in, vs running off of batteries, you can buy transformers with, I think the term is, “center tapped secondary coils”.

Relays and proximity sensors

Richard – I’ll look into that, thanks. Total Harmonic Distortion Figure The datasheet doesn’t give me too much of a clue. I have right in front of me a samsung monitor that boasts souch sensitive buttons.

You could buy one intended for a “quiet” computer And another source to explore would be the suppliers of lab bench power supplies.

It would be good to get away with this as a cheap alternative. Had a bit of a hunt online, pre-empting your reply. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. Maybe I just like doing things the hard way. Unused digital input pins must be tied to an appropriate logic voltage level e.
