The M54HC688 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.
