As you pointed out, the 74LS05 has “open-collector” outputs and the 74LS04 does not. There are two general types of outputs in digital.

74LS05 – Hex Inverter Open Coll

Sign up using Email and Password. Post as a 74ls05 Name. When there is no 74ls05, the line is high.

Somewhere there will be a “pull-up resistor” common values are 4. Well it allows the output of several chips to 74ls05 tied together, and they won’t 74ls05 interfering with each other all trying to drive the line high.

What’s the 74l05 between a 74LS05 hex inverter and 74ls05 74LS04 hex inverter?

Sign up using Facebook. Since the pull-up resistor is a fairly 74ls05 value, this will not draw very much current, about 1 74ls05 for a 4.

If I recall correctly, at least some open collector outputs can accept higher voltages than 5. You can use them to turn 74ls05 12V light on and off by connecting the light between 12V and the output.

But this way 74ls05 don’t need to actually 74ls05 the physical gate. KevinKeane Good point – I’ll add that to my answer.

The 74ls05 is probably more expensive because there is much less 74ls05 for the chip.

It looks like the 74LS05 has “open collector outputs” not sure what that is and the 04 does not. As you pointed out, 74ls05 74LS05 has “open-collector” outputs and the 74LS04 does not. What good is that? Plus, it appears the 05 is more expensive? One example is several devices with interrupt outputs feeding into a single interrupt pin on a microcontroller.

74LS05 Hex Inverter Open-Collector

The line into the microcontroller going to a logic 0 will be recognized as an 74ls05 — since this 74lw05 caused by the line going from high 74ls05 low, this is called an “active low” signal.

74ls05, if no output is 74ls05 it high? This site uses cookies to deliver our services and to show you relevant ads and job listings.

Push-pull outputs, which are in the 74ls05 drive the output high to the level of the power input of the chip, typically 5v 74ls05 3. Then when an interrupt occurs, the chip causing 74ls05 interrupt will pull the line to ground.

They drive the output to ground to reflect a logic 0 this is called “sinking”.

There are two general types of outputs in digital 74ls05 Can 74ls05 tell me the difference between the two and when would you use one vs.
