onsemi 74HC series MM74HC688N is an 8-bit identity comparator designed for high-speed digital applications. This device actively compares two 8-bit data words, outputting a low signal when all corresponding bits are equal (A=B). Featuring a broad operating voltage range from 2V to 6V, it offers typical propagation delays of 30ns at 6V with a 50pF load. The MM74HC688N exhibits low quiescent current of 8 µA and provides output drive capabilities of 5.2mA for both high and low states. Packaged in a 20-pin PDIP (0.300" wide), it is suitable for through-hole mounting. This component finds application in various sectors including industrial control, consumer electronics, and data acquisition systems.
