MC14585BCP集成電路（IC）的比較器規(guī)格書PDF中文資料

MC14585BCP屬于集成電路（IC）的比較器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC14585BCP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(dú)分類。

4?Bit Magnitude Comparator

The MC14585B 4?Bit Magnitude Comparator is constructed with complementary MOS (CMOS) enhancement mode devices. The circuit has eight comparing inputs (A3, B3, A2, B2, A1, B1, A0, B0), three cascading inputs (A B), and three outputs (A B). This device compares two 4?bit words (A and B) and determines whether they are “l(fā)ess than”, “equal to”, or “greater than” by a high level on the appropriate output. For words greater than

4?bits, units can be cascaded by connecting outputs (A > B), (A B) on the least significant (first) comparator are connected to a low, a high, and a low, respectively.

Applications include logic in CPU’s, correction and/or detection of instrumentation conditions, comparator in testers, converters, and controls.
