CD74HC4017中文资料具有 10 个解码输出的高速 CMOS 逻辑十进制计数器/除法器数据手册TI规格书

描述 Description

The ’HC4017 is a high speed silicon gate CMOS 5-stage Johnson counter with 10 decoded outputs. Each of the decoded outputs is normally low and sequentially goes high on the low to high transition clock period of the 10 clock period cycle. The CARRY (TC) output transitions low to high after OUTPUT 10 goes low, and can be used in conjunction with the CLOCK ENABLE (CE\\) to cascade several stages.The CLOCK ENABLE input disables counting when in the high state. A RESET (MR) input is also provided which when taken high sets all the decoded outputs, except \"0\", low.
The device can drive up to 10 low power Schottky equivalent loads.

特性 Features

• Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
• Balanced Propagation Delay and Transition Times
• HC Types
• High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V

简介

CD74HC4017属于集成电路（IC）的计数器除法器。由TI制造生产的CD74HC4017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。
