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 And what part number? The resistors that are in the input of the 74H04 will not play any datashete in limiting the LED current. Post a schematic of what you currently have.
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.
Using open collector as regular 5v output Ask Question. 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.
Email Required, but never shown. Tristian 1 9. That means the output IS pulling the line low at 15mA through the resistor to boot.

What voltage level activates the buffers?
Post as a guest Name. 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.
Dataseet for the comment anyways.

Open collectors outputs are usually used as low side switches by connecting datasheet emitter to the dqtasheet and then feed the ground side of load from the collector. Also, the output is inverted because according to the datasheet the output is the data’s complement.
The datasheets list that max would be 0.
