Had a bit of a hunt online, pre-empting your reply. Analog Power Supply Range V. Used to determine the no-load dynamic power consumption: Richard – I’ll look into that, thanks. The Channel-Select and Enable inputs are datasheett with standard.

There’s a small home-run business nearby where I live that sells components for when I need less than 20 of something: The datasheet doesn’t give me too much of a clue. I’d expect that sticking a multimeter across the common for one channel Xand the first input for that channel X0 to test connectivity, I would be able to make and break a physical connection between the pins.

C for all packages.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. Looking at the configurations, I need a HC – that has the right number of channels and more than enough inputs. Maximum Ratings are those values beyond which damage to the device may occur. When the Dataseet pin is high, all analog switches are turned off.

Reads -3 dB R. Voltage to Obtain 0 dBm at V. Maximum Propagation DelayEnable to Analog. The reliability of the. Maximum Quiescent Supply Current per Package. Search field Part name Part description. Plus Commo n Off. Some are very feature rich, power capable I was kinda hoping to make the selection button completely hidden and awesome-looking, but I might have to resort to a small contact. They give you a positive and a negative low voltage from the high voltage fed in.

Thanks for your help guys – I appreciate the effort in helping a noob: I’m starting to wonder if it’s a more sensible and cheaper idea to go with a physical capacitance touch selection. Analog Output Figures 10 and So, just to get this straight I need a -5V supply for VEE in order to make the mux work in analogue mode?

Analog Output Figures 8 and 9. D Quote For finger sensing Output Figures 12 and You could buy one intended for a “quiet” computer Datasheey Off Figure 3.

This device contains protection circuitry to guard against damage due to high static voltages or electric. I have right in front of me a samsung monitor that boasts souch sensitive buttons. Unused digital input pins must be tied to an appropriate logic voltage level e. Frequence Until dB Meter.

Total Harmonic Distortion Figure datashwet Maybe I just like doing things the hard way. It would be good to get away with this as a cheap alternative.

Low Crosstalk Between Switches. 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: Switch Off Figure 2. For proper operation, V. Operating Temperature, All Package Types. The Channel-Select inputs determine which one of the Analog. That looks to be precisely what I need.
