CD74HC688 高速 CMOS 逻辑 8 位幅度比较器
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.
