This document tackles the basic facts of the 74HCT TTL Compatible CMOS components. It includes a comparison between its sub-family of components. Suggestions on what CMOS to use on a specific ...

I fear the topic of this column is poised to unleash a tsunami of controversy. My engineering accomplice Joe Farr says that this is one of those topics that, when presented to 10 different engineers, ...

The 74HC00 data sheet warns that inputs must not be allowed to float because this makes the output indeterminate. Now, that in itself is a good reason, but there is more… In my previous column, we ...

You can’t leave unused inputs floating, but you might not want to connect them to a power or ground rail either. Digital engineers learned long ago that they should not leave unused inputs unconnected ...

It’s my own fault. I have only myself to blame. I knew I was opening a can of worms when I first thought about writing a column on the topic of applying pull-up and pull-down resistors to the inputs ...
