DESCRIPTION
HCF4517B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP package.
This device 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.
■ CLOCK FREQUENCY 12MHz (Typ.) at VDD = 10V
■ SCHMITT TRIGGER CLOCK INPUTS ALLOWS OPERATION WITH VERY SLOW CLOCK RISE AND FALL TIMES
■ THREE STATE OUTPUTS
■ QUIESCENT CURRENT SPECIFIED UP TO 20V
■ STANDARDIZED, SYMMETRICAL OUTPUT CHARACTERISTCS
■ 5V, 10V AND 15V PARAMETRIC RATINGS
■ INPUT LEAKAGE CURRENT II = 100nA (MAX) AT VDD = 18V TA = 25°C
■ 100% TESTED FOR QUIESCENT CURRENT
■ MEETS ALL REQUIREMENTS OF JEDEC JESD13B "STANDARD SPECIFICATIONS FOR DESCRIPTION OF B SERIES CMOS DEVICES"
