MC14585B中文资料4 位幅度比较器数据手册ONSEMI规格书

描述 Description

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 (AB), and three outputs (AB). This device compares two 4-bit words (A and B) and determines whether they are \"less 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), (AB) 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.

简介

MC14585B属于集成电路（IC）的比较器。由制造生产的MC14585B比较器逻辑比较器系列产品用于根据以数字格式表示的信息比较结果来生成输出；身份型比较器指示两个输入是否相同，幅度型比较器还指示两个输入不相同时哪个较大。它们不同于比较两个模拟输入幅度的器件，后者称为线性比较器且单独分类。
