onsemi 20-SOIC MM74HC688WM

The MM74HC688WM is an 8-bit data comparator in the 74HC logic family, manufactured by multiple vendors. It's designed for comparing two 8-bit words and providing a low output when both inputs are equal (A=B). This device operates with a voltage range of typically 2V to 6V and offers low propagation delay (30ns at 6V and 50pF load) with typical static current consumption of 8 microamps. The package type can vary from DIP to SMD packages like SOP20, and datasheets are available through electronic component distributors such as Huaqiang Electronics Network and others.
