HCF4517B

HCF4517B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP package.

This HCF4517B is a dual 64-stage static shift register consisting of two independent registers each having a clock, data, and write enable input and outputs accessible by stages following the 16th, 32nd, 48th, and 64th stages. These stages also serve as input points allowing data to be put in at the 17th , 33rd, and 49th stages when the write enable input is a logic 1 and the clock goes through a low to high transition. The truth table indicates how the clock and write enable inputs control the operation of HCF4517B. Inputs at the intermediate stages allow entry of 64-bits into the register with 16 clock pulses. The 3-state outputs permit connection of this device to an external bus.
