I have a bunch of chips im trying to communicate with via SPI by chaining all the CLOCK/DATA lines together and hitting each chip-select via a mux. The SPI chips are all active-low, except one. The fucking 74hc595. That fucking piece of shit.

Anyway, so I made a little inverter using a 2n2222 transistors and 2 resistors. I tried it on its own and it works great, but as soon as I wire it into the circuit with the ICs, it does nothing. The output always stays LOW no matter what I pass the input.

Any ideas?
