The Renesas Electronics 8-bit identity comparator built using an advanced dual metal CMOS technology. These devices 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.
A and C grades
Low input and output leakage ≤ 1 μA (max.)
CMOS power levels
High drive outputs (-15 mA IOH, 48 mA IOL)
Meets or exceeds JEDEC standard 18 specifications
Power off disable outputs permit "live insertion"
Available in SOIC and QSOP packages
