PI74FCT521T

Product Description:

Pericom Semiconductor’s PI74FCT series of logic circuits are pro-

duced 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
