The resistors that are in the input of the 74H04 will not play any part in limiting the LED current. Post a schematic of what you currently have.

That means the output IS pulling the line low at 15mA through the resistor to boot. You are essentially creating two paths two ground, which are both variable and not perfect.

What would be the correct way to set it up? IC Timer Working: U2-U5, are they buffers? I’m trying to use the following IC: Please enter your name here.

74 series digital circuit of 7404 74H04 hex inverter

Home Resources Learning Corner. Did you write to the data register? For the series tutorial, turn over to next page. A resource for professional design engineers. Awesome Timer IC Projects.


It consists of only one input and one output. Potential Risks of Artificial Intelligence 18 December You have entered datsaheet incorrect email address! Sign up using Facebook. Using open collector as regular 5v output Ask Question. It supports wide operating conditions and has large operating voltage range. So, using this setup if I would like to drive another IC how would I connect it, I really have a hard time undertanding this Also, the output is inverted because according to the datasheet the output is the data’s complement.

Unless you’re doing level shifting, OC outputs aren’t used to drive other logic inputs. Home Dahasheet Tags Users Unanswered. Please enter your comment! Consumer Sensors for Consumer Electronics.

The bubble in the symbol for a NOT gate at the output port represents the inverting operation. Logic gates are the basic building blocks of dwtasheet electronics.

If you measure the output pin voltage compared to ground, when the output pin should be Low open-collector activewhat do you get? NOT gate is however just on of the series. Basics and Overview of Flip Flops. Monday, December 31, Email Required, but never shown. Reference design for Laser Drive Applications 6 December Internship — Image Processing Engineer 27 December What voltage level activates the buffers?


Thanks for the comment anyways. What the open collector can do when used that way is to either sink current provide ground to the load when ON or leave the output floating high resistance across the transistor when off, the pullup resistor can force a HIGH state while in that high resistance mode.

Open collectors outputs are usually used as low side switches by connecting the emitter to the ground and then feed the ground side of load from the collector.

Power Bank for Smartphones. Typical open collector led setup dstasheet be: Ok, but I don’t have much of choice because thats the only RAM that I have, I know that the 74S is not open collector, but I don’t datsaheet access to it at the moment.

Log into your account. Another consideration is the max current of the 74HC04 chip which is 50mA total and with the LED resistors missing this can be a big problem. There is a C-E voltage drop as well. And what part number? A NOT gate is used to output the Boolean inverse of the applied input.
