I am actually pulsing a 555 timer with amicroprossor to give burst of 40 kHz. I would like to pulse the 555 with 12 volts instead of the five that comes out of the processor. I would like to know of a simple way to turn the 5 volts into 12 volts. The voltage shifter circuit also needs to be able to respond to the fast pulses very well. Thanks
