74 Serie

74 Serie. The 74 series spectrophotometers are ideal for applications in education and routine quality control All units feature a colour touchscreen and intuitive user interface allowing manual free operation 74 Series Spectrophotometers Parameter 7410 7415 Wavelength range 320 to 1000nm 198 to 1000nm Wavelength Accuracy ±20nm.

This page covers a selection of the many ICs in the 74 series concentrating on the most useful gates counters decoders and display drivers For each IC there is a diagram showing the pin arrangement and brief notes explain the function of the pins where necessary For simplicity the family letters after the 74 are omitted in the diagrams below because the pin connections apply to all ICs.

Some manufacturers released some 4000series equivalent CMOS circuits with a 74 prefix for example the 74HC4066 was a replacement for the 4066 with slightly different electrical characteristics (different powersupply voltage ratings higher frequency capabilities lower “on” resistances in analog switches etc).
