Hello,
There is no series resistor for the led.
Put a 470 Ohms resistor in series with the led.
Depending on the type of led, the voltage will be clamped at the forward voltage of the led.

hi Jim,
What would you say the LED current level is.??
LED type and operating voltage.?
E
Its 5V for logical "1" and 0 for logical "0"Hello,
What is the supply voltage of the chip in the simulator?
Bertus
As bertus said, without a series resistor, the output is clamped at the forward voltage of the LED which is about 3.3V in the simulator.I just dont understand where 1.7 volts have gone since i have input 5V and i get 3.3.
Title: Understanding Basic Electronics, 1st Ed.So i have this simple circuit.While my voltage input is 5V why is my output 3.3V? Can someone explain this to me.Thanks in advance!
