description  
These identity comparators perform comparisons  
of two 8-bit binary or BCD words. An  
output-enable (OE) input may be used to force the  
output to the high level.  
GND 10  
The SN54HC688 is characterized for operation  
over the full military temperature range of –55°C  
to 125°C. The SN74HC688 is characterized for  
operation from –40°C to 85°C.
