[1] [2] In the same family are ULN2002A, ULN2004A, as well as ULQ2003A and ULQ2004A, designed for different logic input levels. The ULN2003A is also similar to the ULN2001A (4 inputs) and the ULN2801A, ULN2802A, ULN2803A, ULN2804A and ULN2805A, only differing in logic input levels ( TTL , CMOS , PMOS ) and number of in/outputs (4/7/8).
The 4000 series is a CMOS logic family of integrated circuits (ICs) first introduced in 1968 by RCA. [1] It was slowly migrated into the 4000B buffered series after about 1975. [2] It had a much wider supply voltage range than any contemporary logic family (3V to 18V recommended range for "B" 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 ...
The 74S181 4-bit ALU bitslice resting on a page from the datasheet. The 74181 is a 4-bit slice arithmetic logic unit (ALU), implemented as a 7400 series TTL integrated circuit. Introduced by Texas Instruments in February 1970, [1] it was the first complete ALU on a single chip. [2]
Higher speed than the original 74 series, at the expense of power dissipation. TTL logic levels. [24]: 6–2 [25]: 3–6 74L Low-Power 5 V ±5% 60 ns 3.6 mA −0.2 mA 1967 [26]: 72 Same technology as the original 74 family, but with larger resistors to lower power consumption at the expense of gate speed. TTL logic levels. Now obsolete.
Input column – a blank cell means a normal input for the logic family type. Output column – a blank cell means a "totem pole" output, also known as a push–pull output, with the ability to drive ten standard inputs of the same logic subfamily (fan-out N O = 10). Outputs with higher output currents are often called drivers or buffers.
The GAL22V10 is a series of programmable-logic devices from Lattice Semiconductor, implemented as CMOS-based generic array logic ICs, and available in dual inline packages or plastic leaded chip carriers. It is an example of a standard production GAL device that is often used in educational settings as a basic programmable-logic device.
Front page of a floppy disk controller data sheet (1979) A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to ...
