Note:
Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

Pericom Semiconductor's PI74FCT series of logic circuits are produced in the Company's advanced 0.8 micron CMOS technology, achieving industry leading speed grades.

The PI74FCT521T is an 8-bit identity comparator. When two words of up to eight bits are compared, a bit-for-bit match of the two words provides a LOW output. The comparison of PI74FCT521T can be extended over multiple words by the expansion input. The expansion input IA=B also serves as an active LOW enable input.
