Thanks.What does "through" mean in this context?
You can't pass a 10V peak to peak signal using supplies of 5V and ground.
From the RCA datasheet:
View attachment 261654
mean: turn ON without trig.I do not know what you mean when you say "through".
A switch can turn on or it can turn off.
Your input voltage levels do not say the positive and negative peaks that must be within the power supply range.
Your power supply is +5V and 0V then the input signals must not go above +5V and must not go more negative than 0V.
Thanks.My question as well. Use words that convey some useful information. If the TS is asking why the device turns on when the control input is open, that is wone thing. If the control input is high that is a different concern.
The control voltage is 5V.Are you sure your input switch voltage can be more than Vdd? Maximum Vis from datasheet says not more than Vdd+0.5V (section 6.1 of datasheet, Maximum ratings)
Thanks.I guess TS means all switches are conducting.
Did you check the specs for OFF resistance?
Perhaps your chip is bad, blown by exceeding specs.
Thanks.It is CERTAINLY POSSIBLE to damage an analog switch IC by exceeding the ratings, without causing any visible damage. The input protection diodes that do not appear on every functional diagram will also cause temporary anomalous operation if input voltages exceed the supply voltage.
Without adequately describing the actual conditions there is no way to provide more than guesses.
If you mean the voltages at inputs 1-4 then no, it can't be 'any thing'. See posts 2 and 3, and read the datasheet.the switch voltage can be any thing?
ThanksThe CD4066 application circuit -- Two Sets 10 channels O'scope and Multimeter Multi-Inputs Selector.
Yes, you are right, the datasheet said: Vdd+0.5.If you mean the voltages at inputs 1-4 then no, it can't be 'any thing'. See posts 2 and 3, and read the datasheet.
Thanks.The switch voltage should go between Vcc and Vss (GND), and the signal peaks can be no greater than Vcc to Vss.
Otherwise the switch will not work properly and/or be damaged.
It should be ground.BTW. the drawing below why pin7 goes to 5V? should be GND?
