EC74HC193N chip insides

This is a representation of EveryCircuit’s counter chip.

Function-wise, the counter chip in the simulator is based off of the 74193 chip in the real world (hence the part number in this circuit’s title), but with rising-edge inputs where falling-edge inputs should be irl.

Only the ground sources, LEDs, their series resistors, and logic sources are external components; the rest of the components (including capacitors) make up the chip itself.

Swell! I especially like how you've given the EveryCircuit counter a part number. 😄

Believe it or not, Everycircuit's counter chip is NOT original. It is mainly based off of the 74HC193 chip, with all its inputs rising-edge triggered, as opposed to having some that are falling-edge (like the actual chip irl)

You can Google "74HC193 Datasheet" or go to page 4 of 28 in: https://docs.rs-online.com/ef43/0900766b8151e478.pdf

Good info. I thought the counter was unique to EC. Thanks.

I was always wondering how the counter chip worked. Nicely done!
