UP TO 20V DIP SOP s 5V, 10V AND 15V PARAMETRIC RATINGS s INPUT LEAKAGE CURRENT II = 100nA (MAX) AT VDD = 18V TA = 25°C ORDER CODES s 100% TESTED FOR QUIESCENT CURRENT PACKAGE TUBE T & R s MEETS ALL REQUIREMENTS OF JEDEC DIP HCF4520BEY JESD13B "STANDARD SPECIFICATIONS FOR DESCRIPTION OF B SERIES CMOS SOP HCF4520BM1 HCF4520M013TR DEVICES" incrementing on either the positive-going or DESCRIPTION negative going transitions. For single-unit HCF4520B is a monolithic integrated circuit operations the Enable input is maintained High fabricated in Metal Oxide Semiconductor and the counter advances on each positive going technology available in DIP and SOP packages. transition of the Clock. The counters are cleared HCF4520B, a Dual Binary Up Counter, consists of by high levels on their Reset lines. The counter two identical, internal 4-stage counters. The can be cascaded in the ripple mode by connecting counter stages are D-type Flip-Flops having Q4 to the enable input of the subsequent counter interchangeable Clock and Enable lines for while the clock input of the latter is held low.
