LM239D屬于集成電路（IC）的比較器。由安森美半導體公司制造生產(chǎn)的LM239D比較器邏輯比較器系列產(chǎn)品用于根據(jù)以數(shù)字格式表示的信息比較結(jié)果來生成輸出；身份型比較器指示兩個輸入是否相同，幅度型比較器還指示兩個輸入不相同時哪個較大。它們不同于比較兩個模擬輸入幅度的器件，后者稱為線性比較器且單獨分類。

These comparators are designed for use in level detection, low?level sensing and memory applications in consumer, automotive, and industrial electronic applications.
