DESCRIPTION The M74HC688 is an high speed CMOS 8 BIT EQUALITY COMPARATOR fabricated with silicon gate C2MOS technology. The M74HC688 compares bit for bit two 8-bit words applied on inputs P0 - P7 and inputs Q0 Q7 and indicates whether or not they are equal. A

single active low enable is provided to facilitate cascading several packages to enable comparison of words greater than 8 bits. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
