Hey everyone, essentially right now I'm using a PNP as a low-side switch, with the load on the emitter and the collector grounded. The reason, is I need an active low switch on the ground side, if I moved it to the high side I'd need 8 PNP transistors, to control eight LEDs. I have two groups of 8 LEDs, and want it so one group is turned on when a control signal is high, which an NPN is working great for, but then when the control signal is low I want the other set to be on, so I quickly used a PNP as a low side switch. I know this is inefficient, but can't think of a better way because on the high-side I have a shift register sourcing currents.
Any suggestions?
