TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74ACT521P,TC74ACT521F

8-Bit Equality Comparator

The TC74ACT521 is an advanced high speed CMOS 8-BIT

DIGITAL COMPARATOR fabricated with silicon gate and

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

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.
