74AC520, 74ACT520 Rev. 1.4

74AC520, 74ACT520

8-Bit Identity Comparator

Features

■ Compares two 8-bit words in 6.5ns typ.

■ Expandable to any word length

■ 20-pin package

■ Outputs source/sink 24mA

■ ACT520 has TTL-compatible inputs

General Description

The AC/ACT520 are expandable 8-bit comparators.

They compare two words of up to eight bits each and

provide a LOW output when the two words match bit for

bit. The expansion input IA = B also serves as an active

LOW enable input.

Ordering Information

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
