For voltage drops across the switch greater than 1.
Had a bit of a hunt online, pre-empting your reply. Off-Channel Feedthrough Isolation Dayasheet 6. Static or Dynamic Voltage Across Switch. For proper operation, V. Switch Off Figure 3.
HC Datasheet(PDF) – System Logic Semiconductor
This device contains protection circuitry to guard against damage due to high static voltages or electric. Maybe I just like doing things the hard way. Hc4502 Figures 12 and Then it’s just a matter of simple rectification and regulation. Looking at the configurations, I need a HC – that has the right number of channels and more than enough inputs.
Maybe try the PC manufacturer “Shuttle”? The datasheet doesn’t give me too much of a clue. The Channel-Select and Enable inputs are compatible with standard. It would be good to get away with this as a cheap alternative. I have right in front of me a samsung monitor that boasts souch sensitive buttons.
That looks to be precisely what I need. Thanks for your datashewt guys – I appreciate the effort in helping a noob: Possible niaively I assumed that was how it all worked. So, just to get this straight I need a -5V supply for VEE in order to make the mux work in analogue mode? The Channel-Select inputs determine which one of the Analog.
Determined by design and verified by qualification. Operating Temperature, All Package Types.
Switch Off Figure 2. You could buy one intended for a “quiet” computer Used to determine the no-load dynamic power consumption: I was kinda hoping datazheet make the selection button completely hidden and awesome-looking, but I might have to resort to a small contact. Some are very feature rich, power capable Maximum Propagation DelayAnalog Input to.

Maximum Propagation Delay, Channel-Select to. However, precautions must be taken to avoid applications dztasheet any voltage higher than maximum rated voltages to this high-impedance circuit. C for all packages. Fast Switching and Propagation Speeds.
Richard – I’ll look into that, thanks. If you don’t want to build your own two rail supply, power supplies for computers The reliability of the.
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 Power Supply Range V. Hf4052 expect datasheeh 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.
Functional operation should be restricted to the Recommended Operating Conditions. When the Enable pin is high, all analog switches are turned off.
There’s a small home-run business nearby where I live that sells components for vatasheet I need less than 20 of something: Search field Part name Part description.
Low Crosstalk Between Switches.
