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 ...
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.
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.
Closeup of the pins of a pin grid array The pin grid array at the bottom of prototype Motorola 68020 microprocessor The pin grid array on the bottom of an AMD Phenom X4 9750 processor that uses the AMD AM2+ socket. A pin grid array (PGA) is a type of integrated circuit packaging. In a PGA, the package is square or rectangular, and the pins are ...
A small outline integrated circuit (SOIC) is a surface-mounted integrated circuit (IC) package which occupies an area about 30–50% less than an equivalent dual in-line package (DIP), with a typical thickness being 70% less. They are generally available in the same pin-outs as their counterpart DIP ICs.
Engineer using an early IC-designing workstation to analyze a section of a circuit design cut on rubylith, circa 1979. Integrated circuit design, semiconductor design, chip design or IC design, is a sub-field of electronics engineering, encompassing the particular logic and circuit design techniques required to design integrated circuits, or ICs

In some approaches the floorplan may be a partition of the whole chip area into axis aligned rectangles to be occupied by IC blocks. This partition is subject to various constraints and requirements of optimization: block area, aspect ratios , estimated total measure of interconnects, etc.
