description/ordering information
These identity comparators perform comparisons of two 8-bit binary or BCD words. An output-enable (OE) input
may be used to force the output to the high level.
ORDERING INFORMATION Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines
are available at www.ti.com/sc/package.
