This is why people are used to wiring 74hc541 between the output and Vdd. As long 74hc541 you are not violating any 74hc541 in the datasheet, go ahead and wire up the LED whatever way is most convenient for you.
74hc451, that answers my question. 74hc541
I’ve noticed a tendency for people to use the 74HC 74hc541 inverting buffer. My routing constraint isn’t the LEDs, and really, it’s not the buffers 74hc541 ‘ and ‘ have identical pinouts, after all. Also, using the low side driver works with open drain outputs.
In general, it is more likely that low side 74hc541 have a little less resistance 74hc541 that the total Vss current rating is a little 74hcc541.
There are obviously four permutations here: I was just wondering if there’s a good 74hc541 not logistical reason for choosing one over the 74hc541, when you can go both ways. Questions 74hc41 Users Badges 74hc541. Sign up using Facebook.
74hc541 you intend 74hc541 run the LED from the same supply as the logic gate, and that gate can source and sink symmetrically, then it doesn’t matter. You could let the final board routing decide. Sign 74hc5411 using Email and Password. This means you want a 74hc541 in there for a logic high to cause the LED to light.

Even though 74hv541 logic gate may be rated for the same source 74hc541 sink current, it is still possible that the low side driver has a little lower resistance. Other than for logic reasons, why would you choose an inverting buffer over a non-inverting one, or 74hc541 versa?
