摘　　要：用集成数据选择器可以实现任意组合逻辑函数,实现的方法有代数法和卡诺图法,当逻辑函数变量数较多时,代数法求解过程繁琐,而卡诺图法求解过程较简单。本文给出了用卡诺图法实现任意组合逻辑函数(含约束项和不含约束项两种情况)的方法,教学实践证明,这方法学生容易接受和理解,有较好的教学效果。Combinational logic functions can be completed by integrated-data selectors using algebraic method and Karnaugh map method. As the algebraic method is more complex than the Karnaugh map method when a logic function has several variables,so we use the Karnaugh map method to realize random combinational logic functions（ with or without bound terms）. Teaching practice shows that this method is easy to be accepted and understood by students,and has good teaching effects.
