I have a circuit that uses two types of chips. One set uses 9V, perfect for a 9V battery, and the others use 5V, namely the 74LS04 inverter and the 74LS08 NAND. I want to use resistors to adjust to 5V so all chips can use the 9V battery.
I don't know the internal resistance of the chip, and so am unsure what value of resistor to use.
