7-segment Binary counting from 0-3

It only has a 2-bit input from binary code. It counts in binary code from 0-3, then it decodes it into 4-bit decimal order, then decodes it to 7-segment "8" display.

No prob. I like it cuz it can be built using 3 very common ttl IC's, with only 3 out of 14 gates left unused. Plus, sometimes you really only need to count to 3, not all the way to 9 or whatever- so it's perfect for that!..

Didn't you already do this, @Voltransistor? I mean, I dig it, it just seems familiar.

@Sine_eyed-I like to hear that you have the right ICs. Lol. You should make it on a breadboard. @rbrtkurtz-I don't know, actually. Lol.

Voltran has posted a bunch of 7 segment display circuits, but I couldn't say if this one is identical to any others..

@Voltransistor- it would only take a quad AND gate, quad NOR, a Hex Inverter, a few resistors and a single 7 segment display right?..

You've actually done it a few times, buddy. Search "binary 0-3". I thought it looked familiar. :-)
