SEMICONDUCTOR TECHNICAL DATA  
High–Performance Silicon–Gate CMOS  
The MC54/74HC688 is identical in pinout to the LS688. The device inputs  
are compatible with standard CMOS outputs; with pullup resistors, they are  
compatible with LSTTL outputs.  
The HC688 compares two 8–bit binary or BCD words and indicates  
whether or not they are equal. By using the Cascade Input, two or more of  
the devices may be cascaded to compare words of more than 8 bits.
