I have here an interesting piece of hardware, a CD74HC125E that someone gave me. This chip (can I call this an IC ?) is able to set its outputs to high voltage, low voltage or high impedance.
Do I need to put a resistance in series with the chip if I set an output to either high or low voltage, or is there any current-limiting function in it?
If not, how much current can it take before it burns? I could not figure out where to look in the datasheet.
The datasheet can be found at http://pdf1.alldatasheet.com/datasheet-pdf/view/27005/TI/CD74HC125E.html
