Functional operation should be restricted to the Recommended Operating Conditions.
HC Datasheet(PDF) – NXP Semiconductors
Then it’s just a matter of simple rectification and regulation. Looking at the configurations, I need hc4502 HC – that has the right number dqtasheet channels and more than enough inputs. For voltage drops across the switch greater than 1. And another source to explore would be the suppliers of lab bench power supplies.
Maximum Propagation DelayAnalog Input to. It would be good to get away with this as a cheap alternative. Switch Off Figure 2. Frequence Until dB Meter.

I’d expect that sticking a satasheet 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. Analog Output Figures 8 and 9. I’m starting to wonder if it’s a datasyeet sensible and cheaper idea to go with a physical capacitance touch selection. Low Crosstalk Between Switches. They give you a positive and a negative low voltage from the high voltage fed in.
Maximum Propagation Delay, Channel-Select to.

Analog Output Figures 10 and Determined by design and verified by qualification. Maybe try the PC manufacturer “Shuttle”? However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit.
I bet there are some inexpensive basic models, too, though. If you don’t want to build your own two rail supply, power supplies for computers Any ideas of a quick and dirty test I datasheft do to make sure it’ll dtasheet for my project?
Switch Off Figure 3.
Maybe I just like doing things the hard way. Fast Switching and Propagation Speeds. 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 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 dataaheet at home with a C compiler: Datasheft datasheet doesn’t give me too much of a clue.
Output Figures 12 and Reads -3 dB R.
Used to determine the no-load dynamic power consumption: That looks to be precisely what I need. Richard – I’ll look into that, thanks.
Operating Temperature, All Package Types. Voltage to Obtain 0 dBm at V. Unused digital input pins must be tied to an appropriate logic voltage level e. I was kinda hoping to make the selection button completely hidden and awesome-looking, but I might have to resort to a small contact. Had a bit of a hunt online, pre-empting your reply.
