MC14569B集成电路（IC）的计数器除法器规格书PDF中文资料

MC14569B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MC14569B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。

The MC14569B is a programmable divide−by−N dual 4−bit binary or BCD down counter constructed with MOS P−Channel and N−Channel enhancement mode devices (complementary MOS) in a monolithic structure.

This device has been designed for use with the MC14568B phase comparator/counter in frequency synthesizers, phase−locked loops, and other frequency division applications requiring low power dissipation and/or high noise immunity.

Features

• Speed−up Circuitry for Zero Detection

• Each 4−Bit Counter Can Divide Independently in BCD or Binary Mode

• Can be Cascaded With MC14526B for Frequency Synthesizer Applications

• All Outputs are Buffered

• Schmitt Triggered Clock Conditioning

• Pb−Free Packages are Available*
