Abstract:

The HCF4006B is a monolithic integrated circuit fabricated in metal Oxide Semiconductor technology available in DIP and SOP packages.The HCF4006B comprised of 4 separate"shift register" section; two section of four stages with an output tap at the fourth stage. Each section has an independent "single rail" data path. A common clock signal is used for all stages. Data is shifted to the next stage on negative going transitions of the clock.Through appropriate connections of inputs and outputs, multiple register sections of 4, 5, 8 and 9 stages or single register sections of 10, 12,13,14,16, 17 and 18 can be implemented using one HCF4006B package. Longer shift register sections can be assembled by using more than one HCF4006B. To facilitate cascading stages when clock rise and fall times are slow, an optional output (D1+4™) that is delayed one-half clock-cycle, is provided (see truth table forfrom pin 2)
