Ok, hope some ee major can answer this. I am a cs major with enough know-how to design and build logic using simple MSI parts, but I don't know much about electronics in general. What I need to know is, given a CMOS or TTL output how can I amplify the output so as to be able to drive a small relay (5VDC, 20mA, 250ohm)? I've been glacing at relay drivers in my CMOS book and wasn't sure if I was looking at the right chip or how I was to use it correctly. Thanx.
