The M54/74HC688 utilizes silicon gate C2MOS technology to achieve operating speeds equivalent to LSTTL devices. Along with the low power dissi2 pation and high noise immunity of standard C MOS integrated circuit, it possesses the driving capability of 10 LSTTL load. The M54/74HC688 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 circuit against static discharge and transient excess voltage. October 1992
