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*

簡介

MC14569B屬于集成電路（IC）的計數(shù)器除法器。由制造生產(chǎn)的MC14569B計數(shù)器，除法器計數(shù)器和除法器 IC 是數(shù)字邏輯器件，可對輸入發(fā)生的邏輯轉(zhuǎn)換進行計數(shù)，然后使用多個并行輸出重新發(fā)送累加的計數(shù)，和/或生成單個輸出信號轉(zhuǎn)換，從而對應用某些整數(shù)數(shù)量輸入信號轉(zhuǎn)換進行響應。除了簡單的事件計數(shù)，它們還可用于各種頻率合成應用。
