Since the 74ls05 resistor is a fairly high value, this will not draw very 74ls05 current, about 1 mA for a 4. Questions Tags Users Badges Unanswered. Somewhere there 74ls05 be a “pull-up resistor” common values are 4.

But this way you don’t need to 74ls05 include the physical gate. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms 74ls05 serviceprivacy policy and cookie policyand that your continued use of the website 74ls05 subject to these policies.


Excellent explanation for how OC works. Push-pull outputs, which are in the 74LS04 drive the output high 74ls05 the level of the power input 74ls05 the chip, typically 5v or 3. What good is that? There are two general types of outputs in digital circuitry: KevinKeane Good point 74ls05 I’ll add that to 74ls05 answer. The line into the microcontroller going to a logic 0 will be recognized as an interrupt — since this is caused by the line 74ls05 from high to low, this is called an 74ls05 low” signal.

How, 74ls50 no output is driving it high?

You can 74ls05 them to turn a 12V light on and off by connecting the light between 12V and the output. When there is no interrupt, the line is high. One example is several devices with interrupt outputs feeding into a single interrupt pin on 74ls05 microcontroller. This site uses cookies to deliver our services and to show you relevant ads and job listings. As you pointed out, the 74LS05 74ls05 “open-collector” outputs 74ls05 the 74LS04 does not.

Post as a guest Name. The 74LS05 is probably more 74ls05 because there is much less demand for the chip. One other way to look at it: Then when 74ls05 interrupt occurs, the chip causing the interrupt will pull the line to ground. Sign up or log in Sign up 74ls05 Google.

Plus, it appears the 05 is more expensive?

They drive the output to ground to reflect a logic 74ls05 this is called “sinking”. It looks like the 74ls05 has “open collector 74ls05 not sure what that is and the 04 does not.

Can someone tell me the difference between the two and when 74ls05 you use one vs. 74ls05 the difference between a 74LS05 hex inverter and a 74LS04 hex inverter? If I recall correctly, at least some open collector outputs can accept higher voltages than 5. Regular push-pull outputs are 74ls05 when only one output is driving one or more inputs, which is the case most of the time.
