How can I convert 5V to 3.6V? Is this something that a few diodes will do, or is there a cheap IC that would perform this task? For example NEC makes an 8-pin chip to convert 5V to 2V, but 3.6V seems like an unusual voltage.
I want to provide either 5V or 0V at a pin depending on the state of a 74LS74 output. I'm unfamiliar with analog electronics, but can a transistor be used to do this? If so, how?
I think I'd have the base connected to the TTL output, the collector to the 5V source, and the emitter to the output pin. Not sure if I need to use NPN vs PNP or really anything else.
I see, from looking around it seems like a 74HC4066 does this function (hadn't heard the term transmission gate before). In fact now that I think about it I've seen those used to switch signals around that weren't at TTL levels too, like audio and video signals. Very versatile. Thanks.
