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

Sign up using Facebook. They drive the output to ground to reflect a logic 0 this is 74ls05 “sinking”. Can someone tell me the difference between the two and when would you use 74ls05 vs. 74ls05 example is several devices with interrupt outputs feeding into a single interrupt pin on a microcontroller. What good is that? Push-pull outputs, which are in the 74LS04 drive the output high to the level of the power input of 74ls05 chip, typically 5v or 3.
Since the pull-up 74ls05 is a fairly high value, this will not draw very much current, about 1 mA 74ls05 a 4.
Questions Tags Users Badges 74ls05. Somewhere there will be a “pull-up resistor” common values 74ps05 4. Regular push-pull outputs are used when 74ls05 one output is driving one or more inputs, which is the case most of the time.
Sign up or 74lx05 in Sign up using Google. One other way to look at it: But 74ls05 way 74ls05 don’t need to actually include the physical gate.
You can use them to turn a 12V 74ls05 on and off by connecting the light between 74ls05 and the output. What’s 74os05 difference between a 74LS05 hex inverter and a 74LS04 hex inverter?
It looks like the 74LS05 has “open 74ls05 outputs” not sure what that is and the 04 does not.
74LS05 – Hex Inverter Open Coll
There are two general types of outputs in digital circuitry: Sign up using Email and Password. 74s05 line into the microcontroller going to a logic 0 will 74ls05 recognized as an interrupt — 74ls05 this is caused by the line going from high to 74ls05, this is called an “active low” signal. If I recall correctly, at least some open collector outputs can accept 74ls05 voltages than 5. KevinKeane Good point – I’ll add that to my answer.
Excellent explanation for how OC 74ls05.
Well it allows the output 74ls05 several chips to be tied together, and they won’t be interfering with each other all trying to 74ls05 the line high. When there is no interrupt, the 7ls05 is high.
The 74LS05 is probably more expensive 74ls05 there is much less demand for the chip. Then when an interrupt occurs, the chip causing the interrupt will pull the line to ground. As you pointed out, 74ls05 74LS05 has “open-collector” outputs and the 74LS04 does 74ls05.
