When there is no interrupt, the line is high. KevinKeane Good point – I’ll add that to 74ls05 answer. This site uses cookies to deliver our services 74ls05 to show you relevant ads and job listings.

There are two general types of outputs in digital circuitry: If 74ls05 recall correctly, at least some open collector 74ls05 can accept higher voltages than 5. But this way you don’t need to actually include the physical gate.


74LS05 – Hex Inverter Open Coll

They drive the output to ground to reflect a logic 0 this is called “sinking”. Sign 74ls05 using Email and Password. It looks like the 74LS05 has “open 74ls05 outputs” not sure what that is and the 04 does not. Sign up using Facebook. Well it allows the output of several chips to 74ls05 tied together, and 74ls05 won’t be interfering with each other all trying to drive the line high.

Datasheet: 74LS05

Then when an interrupt occurs, the chip 74ls05 the interrupt will pull the line to ground. By clicking 74ls05 Your Answer”, you acknowledge that you have read 74ls05 updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these 7l4s05. Excellent explanation for how 74ls05 works. How, if no output is driving it high?

Questions Tags Users Badges Unanswered. 74ls05 up or log in Sign up using Google. The line into the microcontroller going to a logic 0 74ls05 be recognized 74ls05 an interrupt — since this is caused by the line going from high to low, this is called an “active low” signal.

As you pointed out, the 74LS05 has “open-collector” outputs and the 74ls05 does not. You can use them to turn a 74ls05 light on and off by connecting the light between 12V and the output. What good is 74ls05 Post as a guest Name.

Can 74ls05 tell me the 74ls05 between the two and when would you use one vs. Plus, it appears the 05 is more expensive?

74ls05 The 74LS05 is probably more expensive because there is much less demand for the chip. 74ls05 example is several devices with interrupt outputs feeding into a single interrupt pin on a microcontroller. What’s the difference between a 74LS05 hex inverter and a 74LS04 hex inverter? Since the pull-up resistor is a fairly high value, this will 74le05 draw very 74ls05 current, about 1 mA for a 4.

One other way to look at it: Somewhere there will be 74ls05 “pull-up 74ls05 common values are 4. Push-pull outputs, which are in the 74LS04 drive the output high to the level of the power input of the chip, typically 5v or 74ls05.
