TI’s CD4040B is a CMOS 12-Stage Ripple-Carry Binary Counter/Divider. Find parameters, ordering and quality information.

The CD4024B types are supplied in 14-lead hermetic dual-in-line ceramic packages (F3A suffix), 14-lead dual-in-line plastic packages (E suffix), 14-lead small-outline packages (M, MT, M96, and NSR suffixes), and 14-lead thin shrink small-outline packages (PW and PWR suffixes).

2021年2月2日 · CD4040 is always available in 16 – pin hermetically sealed dual inline IC package (IC). The output of the IC always comes in TTL, making it very easy to interface it with other TTL, CMOS, and NMOS devices. The IC has many additional features such as high noise immunity and i/O static protection through clamping diodes.

2018年10月3日 · 本电路使用了12级计数器CD4040AE，它可将50Hz的输入脉冲信号变成周期为1分钟的脉冲输出，分频系数为50×60=3000。 把十进制数3000化为二进制的方法是将3000不断地用2除，凡偶数记为“0”，奇数记为“1”，小数点以下的数舍去，直到商等于1为止，于是得到了对应的二进制“101110111000”。 显然，需要七输入与非门进行译码，即每3000个输入脉冲输出一个脉冲。 声明：本文内容及配图由入驻作者撰写或者入驻合作网站授权转载。 文章观点仅代表作 …

如图三所示为0～16小时无级定时控制电路。 该控制器由两级定时器和驱动器组成。 由IC1 (555)和两块l2位二进制计数/分频器IC2、IC3 (CD4040)组成定时电路l，产生0、1、2……14、15小时共16个分挡的可调时间信号。

2022年2月9日 · CD4040 belongs to 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4040 has12-stage Binary/Ripple Counter. CD4040 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family.

CD4040 is ripple-carry binary counters. 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 state. Schmitt trigger action on the input-pulse line permits unlimited rise and fall times.
