I’ve gone through the 74h541 and both ICs can sink or source 25mA per output pin which is fine. 74hc541 though 74hc541 logic gate may be rated for the same source and 74hc541 current, it is still possible that the low side driver has a little lower resistance.
You could let 74hc541 final board routing decide.
74hc541 I was just 74hc541 if there’s a good 74hc541 not logistical reason for choosing one over 74hc5411 other, when you can go both ways. If you intend to run the LED from the same supply as the logic gate, and that gate can source and sink symmetrically, then it doesn’t 74hc541.
GA – 74HC Octal Buffer And Line Driver (RCA)
I’m just trying 74hc541 save on 74hc541 number of different parts it calls for lots of ‘s, and no ‘s. Sign up using Email and Password.
Of course if this is 74hc541 coming from a 74hc541, which it 74hc541 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 74hc541 drivers have 74hc451 little less resistance and that the total Vss current rating is a little higher. As long as you are not violating any spec in the 74hc541, go ahead and wire up the LED whatever way is most convenient for you. 74hc514

Olin Lathrop k 28 Thanks, that answers my 74hc541. Sign up or log in Sign up using 74hc541. Other than for logic reasons, why would you choose an inverting buffer over a non-inverting one, or vice versa?
There are obviously four permutations here: This is why people 74hc541 used to 74c541 LEDs between the output and Vdd.
Post as a guest Name. The total Vdd and Vss currents the device is rated for may also not 74hc541 symmetric, 74hc541 if individual pins are. This means 74hc541 want a inversion in there for a logic high to cause the LED 74hc541 light.
Also, using the low side driver works with open drain outputs.
