A 5-bit input code selects the appropriateword which then appears on the eight outputs.An enable input overrides the address inputs andturns off all eight output transistors.features• Organized as 32 8-bit words• Open collector outputs provide expansion togreater numbers of words• On-chip decoding• 30 ns typical access time• 250 mW typical power dissipation• Input clamp diodesconnection diagramL 151413 1211 10 9MEOUTPUT YlE0 CBINARY SELECTOUTPUTS"AOUTPUTYflY2Y3YOY5 Y6 Y71, 3,156 7I"GNOtypical applicationStUCT218
