NGC 4017 is an intermediate spiral radio galaxy located in the constellation Coma Berenices. Its speed relative to the cosmic microwave background is 3,748 ± 21 km/s, which corresponds to a Hubble distance of 55.3 ± 3.9 Mpc (~180 million ly). [1] NGC 4017 was discovered by German-British astronomer William Herschel in 1785. [2]
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 ...
A very early CD4029A counter IC, in 16-pin ceramic dual in-line package (DIP-16), manufactured by RCA Colorized IC die and schematics of CD4011BE NAND gate. The 4000 series was introduced as the CD4000 COS/MOS series in 1968 by RCA [1] as a lower power and more versatile alternative to the 7400 series of transistor-transistor logic (TTL) chips.
A PMIC may include battery management, voltage regulation, and charging functions.It may include a DC to DC converter to allow dynamic voltage scaling.Some models are known to feature up to 95% power conversion efficiency.
Index Copernicus (IC) is an online database of user-contributed all information, including profiles of scientists, as well as of scientific institutions, publications and projects established in 1999 in Poland, and operated by Index Copernicus International.
English: Pinout of the 4017 decade counter IC. Inputs are green, outputs are blue and power pins are red. Inputs are green, outputs are blue and power pins are red. Date
An engineering change order (ECO), also called an engineering change notice (ECN), engineering change (EC), or engineering release notice(ERN), is an artifact used to implement changes to components or end products.
LM317 with heat sink. The LM317 is an adjustable positive linear voltage regulator.It was designed by Bob Dobkin in 1976 while he worked at National Semiconductor. [1]The LM337 is the negative complement to the LM317, which regulates voltages below a reference.
