HCF4040屬于集成電路（IC）的計(jì)數(shù)器除法器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的HCF4040計(jì)數(shù)器，除法器計(jì)數(shù)器和除法器 IC 是數(shù)字邏輯器件，可對(duì)輸入發(fā)生的邏輯轉(zhuǎn)換進(jìn)行計(jì)數(shù)，然后使用多個(gè)并行輸出重新發(fā)送累加的計(jì)數(shù)，和/或生成單個(gè)輸出信號(hào)轉(zhuǎn)換，從而對(duì)應(yīng)用某些整數(shù)數(shù)量輸入信號(hào)轉(zhuǎn)換進(jìn)行響應(yīng)。除了簡(jiǎn)單的事件計(jì)數(shù)，它們還可用于各種頻率合成應(yīng)用。

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”
