Features

Description

• Cascadable

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.

• Fanout (Over Temperature Range)
