dih said:i saw a circuit diagram for a 1.5v LED flasher.. it has a 74hc14 connected in this way.. how do i connect the pins?
audioguru said:Hi Eric,
You should have told him to look at the datasheet for the 74HC14 pins.
He might need to look at it anyway to see the power supply pins.
dih said:thanks... does it means i need to supply the ic with at least 2v so that it works? without it, the ic wont work huh? damn... i wanted to make a small 1.5v button battery LED flasher.. anyway thanks.. appreciate all the help..
audioguru said:I have some circuits with 74HC14 ICs working with a supply voltage of 1.25V and they might work with a lower supply voltage.
Your circuit nearly doubles the supply voltage to blink the LED.
