Jan 17, 2012 · Page 3 of 11 - Powerful Aquarium Lighting - posted in General Discussion: Hi, Thanks for all the help, so the ATtinys will allow me to control the current and will provide smoother control of the dimming that may get some issues if ran directly from the managed code through the TLCs right? The component portion of the circuit is right from the Datasheet of the LT6550, I will take the CSYNC from the Amiga (Pin 10), the same as Narmi in his Component Schematic and inject it into the Y output. I noticed he has a 680 ohm tied into the Y output. The LT6550 diagram makes no mention of inserting a resistor into the green component output. However, if you were picking a single "best" logic family today it would probably have to be the 74LS00 family. This family arguably has the widest manufacturer support and range of available line of components. The 74LS00 family improves technically on the 7400 family in two key areas: faster speed and lower power consumption.

Aug 25, 2012 · The Datasheet claims it needs 12 volts but if 5 is coming out then feel free to connect the collectors of the transistors to Pin 14. Pin 15 is ground so attach your S-Video grounds to there. If you're still having problems and you're positive you triple checked all the wiring then I recommend posting a picture of what you've done so we can see ...

The K8243 = 74LS04 contains six inverters (NOT gates). These are 5V TTL (transister transistor logic) lower-power Schottky chips. I used to play with them as a kid. Happy days, when some chips contained < 100 transistors! “If both A and B are true, then Q is true” 2-input Transistor AND Gate. A simple 2-input logic AND gate can be constructed using RTL Resistor-transistor switches connected together as shown below with the inputs connected directly to the transistor bases. Short the two inputs of the NAND gate, so that only one input is needed. Now apply the desired input ie '0' or '1'. The output will be of a NOT gate. Hmm, I've found a site called Futurlec that stocks a better range of transistors and FETs. Well, they have the 2n5484 and 2n5486, but I'm assuming they're not much different to the 5485 considering all 3 are on the same datasheet... They also have bulk packs of transistors and resistors and so on. And they have an Australian store to dispatch from.
