alrightee, I'm having a little bit of trouble finding an IC suitable for what I need.
The circuit that I'm designing requires a few transistors to amplify the current coming out of a PIC with one npn 3904 transistor on a few of the I/O pins, but the problem here is it would require 25 of them.
I was wondering if anyone knew of an IC that had a few npn transistors built into them that could be used in place of these 25 single transistors.
they'd need to have something around a current gain of 200hfe.
also, each I/O pin would be powering either a relay, or a small electric motor.
any help would be appreciated.
