Hi All,
I am looking for a simple schematic of an electronic switch. This switch will be driven from a TTL level signal. The output of the switch will be +5 and -5, depending on the input level.
I have used this before, but I do not remember the exact details. I think that it had an NPN and a PNP transistor with the emitters connected, and the +5 fed to the NPN collector through a resistor, and the -5 fed to the PNP collecctor through a resistor. The tied emitters is the switched voltage point.
Thanks for any help on this.
Regards,
mike
