Sourced by many manufacturers, and in multiple similar products, an example of a bipolar transistor operational amplifier is the 741 integrated circuit designed in 1968 by David Fullagar at Fairchild Semiconductor after Bob Widlar's LM301 integrated circuit design. [13]
Some manufacturers released some 4000-series equivalent CMOS circuits with a 74 prefix, for example, the 74HC4066 [2] was a replacement for the 4066 with slightly different electrical characteristics (different power-supply voltage ratings, higher frequency capabilities, lower "on" resistances in analog switches, etc.).
The Widlar circuit may be used with bipolar transistors, MOS transistors, and even vacuum tubes. An example application is the 741 operational amplifier, [4] and Widlar used the circuit as a part in many designs. [5] This circuit is named after its inventor, Bob Widlar, and was patented in 1967.

The following is a list of LM-series integrated circuits. Many were among the first analog integrated circuits commercially produced since late 1965; [1] some were groundbreaking innovations [opinion]. As of 2007, many are still being used. [2] The LM series originated with integrated circuits made by National Semiconductor.
The Soviet integrated circuit designation is different from the Western series: the technology modifications were considered different series and were identified by different numbered prefixes – К155 series is equivalent to plain 74, К555 series is 74LS, К1533 is 74ALS, etc.;
Often, an equivalent circuit is sought that simplifies calculation, and more broadly, that is a simplest form of a more complex circuit in order to aid analysis. [1] In its most common form, an equivalent circuit is made up of linear, passive elements. However, more complex equivalent circuits are used that approximate the nonlinear behavior of ...
U, IC: Integrated circuit (IC) shorter "U" (unit) is preferred instead of "IC" V: Vacuum tube: VR: Voltage regulator (voltage reference), or variable resistor (potentiometer / trimmer / rheostat) voltage regulators are often "U" for IC, pots and trimmers often "R" for resistor X
The combinational logic circuitry of the 74181 integrated circuit. The 74181 is a 7400 series medium-scale integration (MSI) TTL integrated circuit, containing the equivalent of 75 logic gates [3] and most commonly packaged as a 24-pin DIP.
