#106170 - germanium diodes silicon transistors or Responding to: ???'s previous message |
It still doesn't work, even with ideal components. Grounding of input B will still result in a turn-on of transistor, at least partially!
germanium diodes silicon transistors or a darlington would be "ideal behaviour of the components" http://www.cs.ubc.ca/~hilpert/eec/ics/TIDTL.html erik PS what is the 3 transistor setup of the 4554 called? a trillington? |
