Product Description:

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 can be extended over multiple words by the expansion input. The expansion input IA=B also serves as an active LOW enable input.
