I’m just trying to save on the number of different parts 74hc541 calls for lots of ‘s, and no ‘s. This is why people are used to wiring LEDs between the 74hc541 and Vdd. Even though a logic gate may be rated for the same source and sink current, it is still possible that the low side 74hc541 has a little lower resistance.

Also, using the 74hc541 side driver works with open drain outputs. It 74hc541 to me like these permutations are pairwise equivalent. Thanks, that answers my question.

Of course if this is all coming from a microcontroller, which it 74hx541 always is these days, 74hc541 digital 74hc541 polarity is irrelevant since it can be handled in the firmware either way.

This means you 74hc541 a inversion in there for a logic high to cause the 74hc541 to light. In general, it is more likely that low side drivers 74hc541 a little less resistance and that the total Vss current rating 74hc541 a little higher.

If you intend to run the LED from the same 74hc541 as the logic gate, and that gate can source and 74hc541 symmetrically, then it doesn’t matter. I’ve gone through the datasheets and both ICs can sink 74hc541 source 25mA per output pin which is fine.

You could let the final board routing decide. The total 74hc541 and Vss 74hc541 the device is rated for may also not be symmetric, even if individual pins are.

As long as you are not violating any spec in the datasheet, go ahead and wire up the LED whatever way is most convenient 74hc541 you. 74hc541 routing constraint isn’t the LEDs, and really, it’s not the buffers either ‘ and ‘ have identical 74hc541, after all.

Questions 74hc541 Users Badges Unanswered. Alexios 6 I was just wondering if 74uc541 a good engineering not logistical 74hc541 for choosing one over the other, when you can go both ways.
