Hello,
Just a really quick question really, can I connect LEDs straight to the outputs of this without a resistor or will it damage the LEDs?
I am trying to simulate this on a software package and even with no current limiting resistor the LEDs light very dimly.
The circuit that I am adapting is this: Electronic Die I know I could use transistors is needed but I am trying to keep it as simple as possible. I read elsewhere on his website that with the 4000 series you can get about 10mA on the outputs when powering the chip with 9V. The specifcation on my LEDs say they have a max of 30mA so surely no resistor is needed?
Looking forward to hearing from someone. Sorry if it sounds like a really noobish question!
