  3. List of 7400-series integrated circuits - Wikipedia

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

    Conversely, the 4000-series has "borrowed" from the 7400 series – such as the CD40193 and CD40161 being pin-for-pin functional replacements for 74C193 and 74C161. Older TTL parts made by manufacturers such as Signetics , Motorola , Mullard and Siemens may have different numeric prefix and numbering series entirely, such as in the European FJ ...

  4. 7400-series integrated circuits - Wikipedia

    en.wikipedia.org/wiki/7400-series_integrated...

    The first part number in the series, the 7400, is a 14-pin IC containing four two-input NAND gates. Each gate uses two input pins and one output pin, with the remaining two pins being power (+5 V) and ground. This part was made in various through-hole and surface-mount packages, including flat pack and plastic/ceramic dual in-line.

  5. Weight plate - Wikipedia

    en.wikipedia.org/wiki/Weight_plate

    By placing a pin in the stack that causes the cable to pull on each plate above the pin, the weight is selected. We refer to this configuration as a "selectorized" weight machine. [35] Some weight machines, such as the sled-type leg press, or the Smith machine, are designed to be loaded with Olympic plates instead of using a cable-driven stack ...

    en.wikipedia.org/wiki/Steel_design

    The design and use of steel frames are commonly employed in the design of steel structures. More advanced structures include steel plates and shells. In structural engineering, a structure is a body or combination of pieces of the rigid bodies in space that form a fitness system for supporting loads and resisting moments.

    The pilot pin is located in the centre of main contact circle on 4- and 5-pin connectors. On 3-pin (2P+E) connectors, it is located on the contact circle opposite the ground pin. The other connectors are located 105° on either side of the earth pin, rather than 120° as in the smaller variants, to make room for the pilot pin.

  8. Shear pin - Wikipedia

    en.wikipedia.org/wiki/Shear_pin

    The pin itself may be as simple as a metal rod inserted into a channel drilled through two moving parts, locking them in place as long as the pin is intact. It may also be a plain metal rod inserted through a hub and axle; the diameter of the rod, alloy and tempering of the metal, are all carefully chosen to allow the pin to shear only when the ...

    en.wikipedia.org/wiki/Lead_(electronics)

    Several kinds of lead wires. A lead wire is a metal wire connected from the electric pole of an electronics part or an electronic component. The lead wire is a coated copper wire, a tinned copper wire or another electrically conductive wire used to connect two locations electrically.
