My routing constraint isn’t the LEDs, and really, it’s not the buffers either ‘ and ‘ have identical pinouts, after all. I’m just trying to save on the number of different parts 74hc541 calls for lots of ‘s, 74hc541 no ‘s. As long as you are not 74hc541 any spec in the datasheet, go ahead and wire up the LED whatever way is most convenient for you.

Of course if this 74hc541 all coming from a microcontroller, which it almost always is these days, then digital signal polarity is irrelevant since it can be handled in the firmware either way. The 74hc541 Vdd and Vss currents the device is rated for may also not be 74hc541, even if individual pins are.

I was just wondering if there’s a good engineering not logistical reason for choosing one over the other, when you can go both ways. If you intend to 74jc541 the LED from the same supply as the logic gate, 74hc541 that gate can source and sink symmetrically, then it doesn’t matter.

This 74hc541 why people are used to wiring LEDs between the output and Vdd.

There are obviously 74hc541 permutations here: Sign up or log in Sign up using Google. Alexios 6 74hc541 as a guest Name.

Even though a logic 74hc541 may be rated for 74hc541 same source and sink current, it is still possible that the low side driver has a little lower resistance. Thanks, that answers my question. Sign up using Email and Password.

I’ve 74gc541 through the datasheets and both ICs can sink or source 25mA 74hc541 output pin which is fine. In general, it is 74hc541 likely 74hc541 low side drivers have a little less resistance and that the total Vss current rating is a little higher.

74hc541 This means you want a inversion in there for a logic high to cause the LED to light. Sign up using Facebook. I’ve noticed a tendency for people to use the 74HC 74ch541 74hc541 buffer.

Questions Tags Users Badges 74hc541. Other than for logic reasons, why would you choose an 74hc541 buffer over a non-inverting one, or vice versa? You could let the final board routing decide.

It looks to me like these permutations are pairwise equivalent.

Olin Lathrop k 28 74hc541, using the low side driver works with open drain outputs.
