MC14569B数据手册集成电路（IC）的计数器除法器规格书PDF

描述 Description

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.

特性 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*

简介

MC14569B属于集成电路（IC）的计数器除法器。由制造生产的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。
