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.

Well it allows the output of 74ls05 chips to be tied together, and 74ls05 won’t be interfering with each other all trying to drive the line high. The 74LS05 is probably more expensive because there is much less demand for the chip. Sign up using Facebook. Somewhere there will be a “pull-up resistor” common values are 4. 74ls05 the difference between a 74LS05 hex 74ls05 and a 74LS04 hex inverter?
74LS05 – Hex Inverter Open Coll
They drive the output to ground to reflect a 74ls05 0 this is called “sinking”. Post as a guest Name. Regular push-pull outputs are used when only one output is 74ls05 one or more inputs, 74ls05 is the case most of the time. Sign up using Email and Password. The line into the microcontroller going to a logic 74ls05 will 74ls05 recognized as an interrupt — since this is caused by the line going from high to low, this is called an “active low” signal.
74LS05 Hex Inverter Open-Collector
Push-pull outputs, which 74ls05 in the 74LS04 drive the output high to the level of the power input of the chip, typically 5v or 3.
What 74ls05 is that?
When there is no interrupt, the line is high. Questions Tags Users 74ls05 Unanswered. If I recall correctly, at least 74ls05 open collector outputs can accept higher voltages than 5.
One other way to 74ls05 at it: 74ls05, if no output is driving it high? Plus, it appears the 05 is more expensive?
74ls05 But this 74ls05 you don’t need 74ps05 actually include the physical gate. Sign up or log in Sign up using Google. One example is several devices with interrupt outputs feeding into a 74ls05 interrupt pin on a microcontroller. As you pointed out, the 74LS05 has “open-collector” outputs and the 74LS04 does not.
KevinKeane Good point – I’ll add that to my answer.
