"Complementary Metal-Oxide Semiconductor" is a process which implements a combination of PMOS and NMOS transistors. Most current digital logic is implemented in CMOS. Its cost-effectiveness due to being so widespread means many other applications have become common as well, such as in analog design, image sensors, telecommunication, etc.

Will multiple chips outputing onto a bus for a few nanoseconds cause damage?
I'm working on a home-brew CPU design, with the usual mix of parallel EEPROMs, static RAMs and registers, tri-stated onto a single 8 bit bus.
My /output-enable logic for three tristate-able chips on …

Which logic families interpret a floating input as a definite value?
From what I remember, from decades ago, 1980's 5v TTL chips would see a floating input as a zero (because they switched on current, rather than voltage). Update: it seems they were interpreted as one …

Choosing LEDs/resistors to drive directly from 3v3 HC CMOS logic
I'm building a home-brew CPU and I would like to add some blinkenlights, to show the logic state of various signals. (It will run at 1Hz - 100kHz.)
Can I directly drive an LED from a 3v3 74HCxxx out …
