MC14526BDWR2G集成电路（IC）的计数器除法器规格书PDF中文资料

MC14526BDWR2G属于集成电路（IC）的计数器除法器。由安森美半导体公司制造生产的MC14526BDWR2G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。

Presettable 4−Bit Down Counters

The MC14526B binary counter is constructed with MOS P−channel and N−channel enhancement mode devices in a monolithic structure.

This device is presettable, cascadable, synchronous down counter with a decoded “0” state output for divide−by−N applications. In single stage applications the “0” output is applied to the Preset Enable input. The Cascade Feedback input allows cascade divide−by−N operation with no additional gates required. The Inhibit input allows disabling of the pulse counting function. Inhibit may also be used as a negative edge clock.
