Can I use a CA3081 NPN transistor array instead of a bunch of 2N3904 transistors to drive a bunch of MOSFETs?
I was going to drive a MOSFET from an ESP32 (3.3 V output) with a 2N3904 NPN transistor like this:
I will need 24 MOSFETs in my project, and that is a lot of soldering.
I found the CA3081 general ...

In the circuit below, in the section inside the green circle,
it seems there's no purpose for connecting the NPN transistor's collector, to the base of the other NPN transistor on the right.
