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.

Sign up using Email and Password. If you measure the output pin voltage compared to ground, when the output pin should be Low open-collector active dagasheet, what do you get? Open collectors outputs are usually used as low datqsheet switches by connecting the emitter to the ground and then feed the ground side of load from the collector. That means the output IS pulling the line low at 15mA through the resistor to boot.
It supports wide operating conditions and has large operating voltage daasheet. Basics and Overview of Flip Flops.

Did you write to the data register? For the series tutorial, turn over to next page. Please enter your name here. There is a C-E voltage drop as well.
Also, the output is inverted because according to the datasheet the output is the data’s complement.

The resistors that are in the input of the 74H04 will not play any part in limiting the LED current.
