TC74HCT688AP/AF  
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic  
TC74HCT688AP,TC74HCT688AF  
8-Bit Equality Comparator  
The TC74HCT688A is a high speed CMOS 8-BIT EQUALITY  
COMPARATOR fabricated with silicon gate C2MOS technology.  
TC74HCT688AP  
It achieves the high speed operation similar to equivalent  
LSTTL while maintaining the CMOS low power dissipation.  
This device may be used as a level converter for interfacing  
TTL or NMOS to High Speed CMOS. The inputs are compatible  
with TTL, NMOS and CMOS output voltage leveles.  
The TC74HCT688A compares two 8-bit binary or BCD words  
applied inputs P ~P , and inputs Q ~Q , and indicates whether  
0

or not they are equal.  
A signal active low enable is provided to facilitate cascading of  
several packege to compare of words greater than 8 bits.  
All inputs are equipped with protection circuits against atatic  
discharge or transient excess voltage.
