i’m thinking of using a CD4066B CMOS Quad Bilateral Switch in an Arduino project. i understand it can handle ±7.5V or +15V as the voltage it is switching (logic is 5V and ~20mAh).
But i can’t seem to understand what is the switching current for these 15volts.
Can it switch for example 11V and 900mAh per channel (it has 4 channels)??
Here is the chip datasheet:
No. Use a relay.
Thanks for the reply.
My problem is that there are extremely limited weight and size limitations for switching power in this project. As well there is a need to switch around 10 channels - hence i’m looking for a chip that weight ~1 gram, which can handle several channels, rather than using 10 times a solid state or a mechanical rely, which add up to more than 50 grams and 3 match boxes volume, which is a lot in this case.
Do you know of a small chip that does what the CD4066B CMOS Quad Bilateral Switch does and has the same small chip size - but rather can handle around 1-2 Amps of current?
Do you have a common ground or power to these 10 channels or are they all isolated? If they’re isolated, start looking at high current optocouplers. If there’s a common then there are any number of high/low side switching ICs that will work.
They don’t have a common ground.
The situation seems to be that all is working well with 10 of the following relays and what i need is a chip that does just the same, but is smaller and weighs less.
Here are the relays model that i want to replace with an IC:
