TC74ACT521P,TC74ACT521F  
8-Bit Equality Comparator  
TC74ACT521P  
The TC74ACT521 is an advanced high speed CMOS 8-BIT  
DIGITAL COMPARATOR fabricated with silicon gate and  
double-layer metal wiring C2MOS technology.  
It achieves the high speed operation similar to equivalent  
Bipolar Schottky TTL 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 levels.  
It compares two 8-bit binary or BCD words applied inputs  
TC74ACT521F  
P ~P , and inputs Q ~Q , and indicates whether or not they are

equal.  
A signal active low enable is provided to facilitate cascading of  
several packages to compare of words greater than 8 bits.  
All inputs are equipped with protection circuits against static  
discharge or transient excess voltage.
