CD54HC688中文资料具有使能端的 8 位等值/幅度比较器 (P=Q)数据手册TI规格书

描述 Description

The ’HC688 and ’HCT688 are 8-bit magnitude comparators designed for use in computer and logic applications that require the comparison of two 8-bit binary words. When the compared words are equal the output (Y) is low and can be used as the enabling input for the next device in a cascaded application.
