Descriptions
Descriptions of onsemi 74AC521SCX provided by its distributors.
Identity Comparator 8-Bit 20-Pin SOIC W T/R / IC COMPARATOR IDENTITY 8B 20SOIC
Identity Comparator, AC Series, 8-Bit, Inverted Output, CMOS, PDSO20
Fact AC/ACT CMOS Logic 8-Bit Identity Comp
The AC/ACT521 is an expandable 8-bit comparator. It compares two words of up to eight bits each and provides a LOW output when the two words match bit for bit. The expansion input I#A = B also serves as an active LOW enable input. Product Highlights: ICC reduced by 50% Compares two 8-bit words in 6.5 ns typ Expandable to any word length 20-pin package Outputs source/sink 24 mA ACT521 has TTL-compatible inputs
