8-Bit Equality Comparator
The TC74ACT521 is an advanced high speed CMOS 8-BIT
DIGITAL COMPARATOR fabricated with silicon gate and
double-layer metal wiring C
2
MOS 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

, 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.
