Hi, community!
I've recently tried to use 74HC4051 multiplexer in order to control my 6 LEDs (let's call the like this) with just 4 outputs from Teensy 3.6. So I am sending signals from Teensy to Mux.
The test went successfully, but there's one thing I wasn't aware of. The Mux doesn't retain the values sent. E.g:
Each of my LEDs is ON when the HIGH signal is sent, and is OFF when LOW signal is sent.
If I send the HIGH value to my first LED - it is ON, but as soon as I change the channel on Mux to address my second LED, the first LED goes OFF.
I need to be able to retain values sent to LEDs until the LOW signal is sent to them. Is there a way to achieve this with the Mux? Or do I need to add anything to my chain?
