Hi, I am new to the Arduino, I have a project I am working on to test wiring harness. This section will describe each pin you will need to use. In your attempt to short one output to the other, one will pull high while the other will pull low.

There is no advantage to shorting them together if you stay within the recommended fanout the number of inputs an output can drive and there could be bad side effects such as a brief shoot-through that causes a glitch if the paths through the decoder are not identical in delay time.

June 74lsn datasheet, 0 Comments. So instead of using an AND gate, I was wondering if i can just short them.

It would “mess things up”. Email Required, but never shown. Notify me of new posts 74ls154 email. Let’s say for two inputs, the output values will be the same. Please check the attached logisim screenshot to get a better idea of what I’m trying to do.

If you connect two outputs together and they are not in the same state which they won’t be for a 1-of-N decoder you will get a short circuit between Vcc and GND through those two pins. Any pointers would be helpful.

Data sheet says that the outputs are ” High fan-out, totem-pole, low impedance outputs”. I was wondering if you can control multiple 74hc with the 74lsn.
