    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 ...

    en.wikipedia.org/wiki/Reconfigurable_optical_add...

    In optical communication, a reconfigurable optical add-drop multiplexer (ROADM) is a form of optical add-drop multiplexer that adds the ability to remotely switch traffic from a wavelength-division multiplexing (WDM) system at the wavelength layer. This is achieved through the use of a wavelength selective switching module.

    en.wikipedia.org/wiki/Optical_add-drop_multiplexer

    Optical add-drop multiplexer, using a fiber Bragg grating and two circulators. An optical add-drop multiplexer ( OADM ) is a device used in wavelength-division multiplexing (WDM) systems for multiplexing and routing different channels of light into or out of a single-mode fiber (SMF).

  6. Multiplexer - Wikipedia

    en.wikipedia.org/wiki/Multiplexer

    An electronic multiplexer can be considered as a multiple-input, single-output switch, and a demultiplexer as a single-input, multiple-output switch. [3] The schematic symbol for a multiplexer is an isosceles trapezoid with the longer parallel side containing the input pins and the short parallel side containing the output pin. [ 4 ]

    Optional CIC61508 safety monitor. Arduino IDE supported via add-in, plus Eclipse-based tools with multicore debugger. MBZ Pro WiFi Atmega328P-PU MaxBlitz: MBZ Pro Mega is an Arduino compatible stand-alone board with a prototyping area and built-in Wi-Fi. Featuring a compact design, it helps to shrink Arduino projects and make it permanent.

  8. Add-drop multiplexer - Wikipedia

    en.wikipedia.org/wiki/Add-drop_multiplexer

    An add-drop multiplexer also has the capability to add one or more lower-bandwidth signals to an existing high-bandwidth data stream, and at the same time can extract or drop other low-bandwidth signals, removing them from the stream and redirecting them to some other network path. This is used as a local "on-ramp" and "off-ramp" to the high ...

  9. Barrel shifter - Wikipedia

    en.wikipedia.org/wiki/Barrel_shifter

    The very fastest shifters are implemented as full crossbars, in a manner similar to the 4-bit shifter depicted above, only larger. These incur the least delay, with the output always a single gate delay behind the input to be shifted (after allowing the small time needed for the shift count decoder to settle; this penalty, however, is only incurred when the shift count changes).
