Description  
The HD74HCT688 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.  
This device is useful in memory block decoding applications, where memory block enable signals must be generated  
from computer address information.  
Features  
LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility  
High Speed Operation: tpd (Data to P=Q) = 18 ns typ (CL = 50 pF)  
High Output Current: Fanout of 10 LSTTL Loads  
Wide Operating Voltage: VCC = 4.5 to 5.5 V  
Low Input Current: 1 µA max  
Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
