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.

74hc541 gone through the datasheets and both ICs can sink or source 25mA per output pin which is fine. Sign up or log in Sign up using Google. This site uses cookies to deliver our services and to show you relevant ads and job listings.

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.


It looks to me like these permutations are 744hc541 equivalent. The total Vdd and Vss currents the device is rated for may also not be symmetric, even if individual pins are. By using our 74hc541, you acknowledge that 744hc541 have read and understand our Cookie 74hc541Privacy Policyand our Terms of Service. Alexios 6 Of course if this is all coming 74hc541 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.

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.

I’m just 74hc541 to save on the number of different parts it calls for lots of ‘s, 74hc541 no ‘s.

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?
