  2. IC power-supply pin - Wikipedia

    en.wikipedia.org/wiki/IC_power-supply_pin

    IC power-supply pins are voltage and current supply terminals found on integrated circuits (ICs) in electrical engineering, electronic engineering, and integrated circuit design. [ a ] ICs have at least two pins that connect to the power rails of the circuit in which they are installed.

  3. List of 4000-series integrated circuits - Wikipedia

    en.wikipedia.org/wiki/List_of_4000-series...

    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 ...

  6. List of 7400-series integrated circuits - Wikipedia

    en.wikipedia.org/wiki/List_of_7400-series...

    Parts in this section have a pin count of 14 pins or more. The lower part numbers were established in the 1960s and 1970s, then higher part numbers were added incrementally over decades. IC manufacturers continue to make a core subset of this group, but many of these part numbers are considered obsolete and no longer manufactured.

    VIN on a Chinese moped VIN on a 1996 Porsche 993 GT2 VIN visible in the windshield VIN recorded on a Chinese vehicle licence. A vehicle identification number (VIN; also called a chassis number or frame number) is a unique code, including a serial number, used by the automotive industry to identify individual motor vehicles, towed vehicles, motorcycles, scooters and mopeds, as defined by the ...

  9. Routing (electronic design automation) - Wikipedia

    en.wikipedia.org/wiki/Routing_(electronic_design...

    In electronic design, wire routing, commonly called simply routing, is a step in the design of printed circuit boards (PCBs) and integrated circuits (ICs). It builds on a preceding step, called placement, which determines the location of each active element of an IC or component on a PCB.
