     12-Stage Binary Ripple Counter

    产品信息

    The MC74AC4040 consists of 12 master-slave flip-flops. The output of each flip-flop feeds the next and the frequency at each output is half that of the preceding one. The state of the counter advances on the negative-going edge of the Clock input. Reset is asynchronous and active-high.
    State changes of the Q outputs do not occur simultaneously because of internal ripple delays. Therefore, decoded output signals are subject to decoding spikes and may have to be gated with the Clock of the MC74AC4040 for some designs.
    • 140 MHz Typ. Clock
    • Outputs Source/Sink 24 mA
    • Operating Voltage Range: 2.0 to 6.0 V
    • High Noise Immunity
    • These devices are available in Pb-free package(s). Specifications herein apply to both standard and Pb-free devices. Please see our website at www.onsemi.com for specific Pb-free orderable part numbers, or contact your local ON Semiconductor sales office or representative.

    型号制造商描述购买
    MC74AC4040DR2GONMC74AC4040 由 12 个主-从触发器组成。每个触发器的输出馈送到下一个触发器,每个输出处的频率为上一个的一半。计数器的状态在时钟输入的负向边前进一次。重置为异步和有效高电平。由于内部波纹延迟,Q 输出的状态变化不会同时发生。因此,解码的输出信号容易发生解码尖峰,对于某些设计可能必须使用 MC74AC4040 的时钟进行门控。 立即购买
