Hi sir,
The input will go to a 74ls244, an octal buffer.
It looks like this.
Vcc----resistor----(x)--->to input of 74ls244.
On (x), a switch is present that connects to ground when a logic zero is wanted.
I'll have to check on the datasheet Vih(high level input voltage), Vil(low level input voltage) etc. so I know what range the voltage should be to ensure a logic 1 or a logic 0. The other parameters are low level input current, or high level input current. This will allow me to choose what value of resistor to use.
