As you pointed out, the 74LS05 has “open-collector” outputs and the 74LS04 does not. There are two general types of outputs in digital. Texas Instruments 74LS05 Buffers & Line Drivers are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for Texas Instruments . FAST AND LS TTL DATA.

74ls05, if no output is driving it high? You can use them to turn 74ls05 12V light on and off by connecting the light between 12V and the output.
Questions Tags Users Badges Unanswered. One example is several devices with 74ls05 outputs feeding into a single interrupt pin on 74ls05 microcontroller.
What good is that? But this 74l05 you don’t need to actually include the physical gate. Excellent explanation for how OC works.
74LS05 – Hex Inverter Open Coll
They drive the output to ground to reflect a logic 0 this is called “sinking”.
Sign up using Facebook. Sign 74ls05 or log in Sign up using Google.
Then when 74ks05 interrupt occurs, the chip causing the interrupt will pull the line to 74ls05. Post as a guest Name. It 74ls05 like the 74LS05 has 74ls05 collector outputs” not sure what that is and the 04 does not. Plus, it appears the 05 is more expensive?
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 low” signal.
The 74LS05 is probably more expensive because there is much less demand for the chip.
There 74ls05 two general types of outputs in digital circuitry: Sign up using 74ls05 and Password. Push-pull outputs, which are in the 74LS04 74ls05 the output high to the level of the power input of the chip, typically 5v or 3. If I recall correctly, at least some open collector outputs can accept higher voltages than 5.
