Additional preview pages of the HD74HC688 datasheet.

The HD74HC688 compares 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 comparison of words greater than 8-bits.

High Speed Operation: tpd (P or Q to Output) = 17 ns typ (CL = 50 pF).
High Output Current: Fanout of 10 LSTTL Loads.
Wide Operating Voltage: VCC = 2 to 6 V.
Low Input Current: 1 µA max.
Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C).
