You have entered an incorrect email address! U2-U5, are they buffers? Tristian 1 9. Email Required, but never shown.

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. 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 Thanks for the comment anyways. Reference design for Laser Drive Applications 6 December What voltage level activates the buffers?

Ideally, the supply voltage should range between 5. Project Engineer 22 December Awesome Timer IC Projects. 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.

It consists of only one input and one output. Typical open collector led setup would be: The datasheets list that max would be 0. Logic gates are the basic building blocks of digital electronics. NOT gate is however just on of the series.

Sign up using Facebook. 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 have access to it at the moment. The resistors that are in the input of the 74H04 will not play any part in limiting the LED current.

If you measure the output pin voltage compared to ground, when the output pin should be Low open-collector activewhat do you get? Please enter your name here. And what part number?

Unless you’re doing level shifting, OC outputs aren’t used to drive other logic inputs. That means the output IS pulling the line low at 15mA through the resistor to boot.
