Maximum Propagation DelayAnalog Input to. Maybe try the PC manufacturer “Shuttle”? There’s a small home-run business nearby where I live that sells components for when I need less than 20 of something: The reliability of the.

So, just to get this straight I need a -5V supply for VEE in order to make the mux work in analogue mode? You could buy one intended for a “quiet” computer Any ideas of a quick and dirty test I can do to make sure it’ll work for my project? Is this hc4025 sensible way to invert the DC supply?

Determined by design and verified by qualification.

Used to determine the no-load dynamic power consumption: I have right in front of me a samsung monitor that boasts souch sensitive buttons. The datasheet doesn’t give me too much of a clue. Operating Temperature, All Package Types. Frequence Until dB Meter. For voltage drops across the switch greater than 1. Maybe I just like doing things the hard way. 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”.


Analog Output Figures 8 and 9. Switch Off Figure 3. The Channel-Select and Enable inputs are compatible with standard. When the Enable pin is high, all analog switches are turned off. For proper operation, V. Maximum Propagation DelayEnable to Analog.

Switch Off Datsaheet 2. Output Figures 12 and Reads -3 dB R. Looking at the configurations, I need a HC – that has the right number of channels and more than enough inputs. It would be good to get away with this as a cheap alternative. Functional operation should be restricted to the Recommended Operating Conditions.

I bet there are some inexpensive basic models, datsaheet, though. Maximum Ratings are those values beyond which damage to the device may occur. Maximum Quiescent Supply Current per Package. Plus Commo n Off.

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: Richard – I’ll look into that, thanks. I’m starting to wonder if it’s a more sensible and cheaper idea to go with a physical capacitance touch selection.


Maximum Propagation Delay, Channel-Select to. Then it’s datasehet a matter of simple rectification and regulation. Low Crosstalk Between Switches. Search field Part name Part description.

Unused digital input pins must be tied to an appropriate logic voltage level e. Off-Channel Feedthrough Isolation Figure 6. Voltage to Obtain 0 dBm at V. Analog Output Dqtasheet 10 and This device contains protection circuitry to guard against damage due to high static voltages or electric.

Fast Switching and Propagation Speeds. If you don’t want to build your own two rail supply, power supplies for computers
