DESCRIPTION

The HCF4040B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. The HCF4040B is a ripple carry binary counter. All counter stages are master-slave flip-flops. The state of a counter advances one count on the 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.

■ MEDIUM SPEED OPERATION : tPD = 80ns (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

■ MEETS ALL REQUIREMENTS OF JEDEC JESD13B ” STANDARD SPECIFICATIONS FOR DESCRIPTION OF B SERIES CMOS DEVICES”

HCF4040属于集成电路（IC） > 计数器，除法器。意法半导体（ST）集团制造生产的HCF4040计数器，除法器计数器和除法器 IC 是数字逻辑器件，可对输入发生的逻辑转换进行计数，然后使用多个并行输出重新发送累加的计数，和/或生成单个输出信号转换，从而对应用某些整数数量输入信号转换进行响应。除了简单的事件计数，它们还可用于各种频率合成应用。
