描述 Description

General Description
The CD4020BC, CD4060BC are 14-stage ripple carry binary counters, and the CD4040BC is a 12-stage ripple carry binary counter. The counters are advanced one count on the negative transition of each clock pulse. The counters are reset to the zero state by a logical “1” at the reset input independent of clock.

特性 Features

■ Wide supply voltage range: 3.0V to 15V
■ High noise immunity: 0.45 VDD (typ.)
■ Low power TTL compatibility: Fan out of 2 driving 74L or 1 driving 74LS
■ Medium speed operation: 8 MHz typ. at VDD = 10V
■ Schmitt trigger clock input

简介

CD4020BC属于集成电路（IC）的计数器除法器。由制造生产的CD4020BC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。
