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 ...

The three main logic families in the 1980s were TTL, ECL, and CMOS. The three main logic families in the 1980s were TTL, ECL, and CMOS. In my previous column, we started our look at logic data sheets ...

Before we plunge headfirst into the fray with gusto and abandon (and aplomb, of course), let’s remind and reassure ourselves that—although the following discussions focus on the devices and ...

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 ...

Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in terms ...

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, ...
