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

Well it allows the output of several chips to be tied together, and they won’t be interfering with each other all 74ls05 to drive the line high. Then when an interrupt occurs, the chip causing the interrupt will pull the line to 74ls05. Can someone tell me the difference between the two 74ls05 when would you use one vs.
Sign up or log in Sign up using Google. There are two general types of outputs in digital circuitry: Questions 74ls05 Users Badges Unanswered. Push-pull outputs, which are in the 74LS04 drive the output high to the level of the power 74ls05 of the chip, typically 5v or 3.
Somewhere there will be 74ls05 “pull-up resistor” common values are 4. Plus, it appears the 05 is more expensive?
What good is that? What’s the difference between a 74LS05 hex inverter and a 74LS04 hex inverter? 74ls05 Good point – I’ll add that to my answer. Excellent explanation for how OC works. 74ls05 example is several devices with interrupt outputs feeding 74ls05 a single interrupt pin 74lw05 a microcontroller.

Sign up using Email and Password. How, if no output is driving 74ls05 high? Sign up using Facebook. But this 74ls05 you don’t need to actually include the physical gate.
74ls05 Since the pull-up resistor is a fairly 74ls05 value, this will not draw very much current, about 1 mA for a 4. They drive the output to ground to reflect a logic 0 this is 74ls05 “sinking”. When there is no interrupt, the line is high.

Post as 74ls05 guest 74ls05. The line into the microcontroller going to a logic 0 will be recognized as an interrupt — since this is caused by the line going from high to low, this is called an “active 74ls05 signal.
One other way to look at it: If I recall 74ls05, at least some open collector outputs can accept higher voltages than 5. The 74LS05 is probably 47ls05 expensive because there is much less demand for the chip.
