CMOS IC 因为具有功耗低、单双电源工作、电压范围宽、噪声容限大等优点,因此作为设计系统装置时的逻辑组件使用是很适合的。在一个系统装置中,除CMOS IC 组件外常常还有其他元器件,因此CMOS与这些元器件之间如何进行连接是很重要的。所谓接口电路是指逻辑电平不同的组件或组件与元器件相互连接的电路。本文按三部分作简单介绍:一、与非CMOSIC 组件(NMOS、TTL,ECL)的接口电路; Because CMOS ICs have the advantages of low power consumption, single and dual power supply, wide voltage range and large noise margin, CMOS ICs are suitable as logic components for designing system devices. In a system setup, there are often other components besides CMOS IC components, so it is important how the CMOS is connected to these components. The so-called interface circuit refers to the logic level of different components or components and components interconnected circuit. This article is based on three parts for a brief introduction: First, and non-CMOSIC components (NMOS, TTL, ECL) interface circuit;
