HCF4020B RIPPLE-CARRY BINARY COUNTER/DIVIDERS 14 STAGE ■ ■ ■ ■ ■ ■ ■ ■ ■ MEDIUM SPEED OPERATION: 16MHz (Typ.) at VDD = 10V FULLY STATIC OPERATION COMMON RESET BUFFERED INPUTS AND OUTPUTS STANDARDIZED SYMMETRICAL OUTPUT CHARACTERISTICS QUIESCENT CURRENT SPECIFIED UP TO 20V 5V, 10V AND 15V PARAMETRIC RATINGS INPUT LEAKAGE CURRENT II = 100nA (MAX) AT VDD = 18V TA = 25°C 100% TESTED FOR QUIESCENT CURRENT DESCRIPTION HCF4020B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. HCF4020B is a ripple carry binary counter. All counter stages are master-slave flip-flops. The state of a counter advances one count on the DIP SOP ORDER CODES PACKAGE TUBE T&R DIP SOP HCF4020BEY HCF4020BM1 HCF4020M013TR negative transition of each input pulse; a high level on the RESET line resets the counter to its all zeros stage. Schmitt trigger action on the input pulse line permits unlimited clock rise and fall times. All inputs and outputs are buffered.
