Hi,
I am having some confusion regarding pull down resistors. In the schematic I have a 100k pulldown resistor. P1 is the output port and the nOE(OE bar) is the input to a buffer.
What is confusing me is if the P1 input is high impedance then the nOE should go high, but when the P1 pin goes low isn't the nOE stuck again at high as the Vcc is never cutoff?
