Hello all,
Say I have 4 signals all in parallel. Rather than using transistors to control each individual line, what kind of IC or setup could I buy/make so that I can simply turn on, or off, all four signals at once. Like a transistor w/ four individual bases and emitters. Thanks a lot.

Are the 4 signals you need to turn off and on, digital signals or analog signals?

If analog, what is the voltage range associated with the signals?

It's digital

 

An SPST Analog switch such as a 4066 should do the trick.

 

For 4 digital signals, the old 74LS125 or 126 is just the thing. Use the three state enables to turn the outputs on or off.

 

Perfect! That was exacly what I was looking for.
Thanks so much
