The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
Delay calculation is the term used in integrated circuit design for the calculation of the gate delay of a single logic gate and the wires attached to it. By contrast, static timing analysis computes the delays of entire paths, using delay calculation to determine the delay of each gate and wire.
The 555 timer IC is an integrated circuit used in a variety of timer, delay, pulse generation, and oscillator applications. It is one of the most popular timing ICs due to its flexibility and price. Derivatives provide two or four timing circuits in one package. [2]
A timing diagram can contain many rows, usually one of them being the clock. It is a tool commonly used in digital electronics, hardware debugging, and digital communications. Besides providing an overall description of the timing relationships, the digital timing diagram can help find and diagnose digital logic hazards .
The timer may switch equipment on, off, or both, at a preset time or times, after a preset interval, or cyclically. A countdown time switch switches power, usually off, after a preset time. A cyclical timer switches equipment both on and off at preset times over a period, then repeats the cycle; the period is usually 24 hours or 7 days.
Intel 4004 CPU and associated chips on the circuit board from a Busicom calculator The result of the discussions between Intel and Busicom was an architecture that reduced the 7-chip Busicom design to a 4-chip Intel proposal composed of CPU, ROM, RAM and I/O (input-output) devices.

Basic fixed-threshold comparator and its derivatives - simple time delay relay and cascaded window monitor. To ensure fast turn-off transients, load resistor RL should provide on-state current of at least 5 mA [39] The simplest TL431-based comparator circuit requires a single external resistor to limit I CA at around 5 mA.
