74LV4052 Dual 4-channel analog multiplexer/demultiplexer
I currently am using a multiplexor to connected to one analog channel from my Arduino. The multiplexor is connected to 4 pressure sensors that draw approximately 100mA while in use.
Because I don't want to keep my pressure sensors powered on all the time, I want to use a NPN transistor to complete the circuit.
However I want to complete the circuit by using the same combinations of GPIO's high and low that I am using for the multiplexor.
My current design is using a demux to help me bring the proper transistors high or low. I would tie in the same GPIO's that I use for the multiplexor to keep the sensors powered on and readings acquired in sync.
I just stumbled upon a IC that is a multiplexor/demultiplexer (dual)
I am not familiar with the component, would I be able to simplify my project by using the component listed above?
I understand I need the transistors to complete the circuit because I can not achieve enough current with the demultiplexer.
I appreciate your help in advanced, please let me know if you would like further clarification.
