HD74HC688 Datasheet | Hitachi Semiconductor

8-bit Magnitude parator Description The HD74HC688 pares bit for bit two 8-bit words and indicates whether or not they are equal. The P=Q output indicates equality when it is low. A single active low enable is provided to facilitate cascading of several packages and enable parison of words greater than 8-bits. This device is useful in memory block decoding applications, where memory block enable signals must be generated from puter address information.
