Looking at the component library, for 74HC series chips I only see 2V, 4V, and 6V voltage options:
What should I do if I want the component to output TTL-friendly 5V signals?
The data sheet I have from TI says that the chip outputs VCC for logic high but even if I connect 5V to the hidden VCC pin in Multisim it still outputs 2/4/6 volts.
