| HD74AC280 9-bit Parity Generator/Checker REJ03D0266-0200Z (Previous ADE-205-387 (Z)) Rev.2.00 Jul.16.2004 Description The HD74AC280 is a high-speed parity generator/checker that accepts nine bits of input data and detects whether an even or an odd number of these inputs is High. If an even number of inputs is High, the Sum Even output is High. If an odd number is High, the Sum Even output is Low. The Sum Odd output is the complement of the Sum Even output. Features * Outputs Source/Sink 24 mA * Ordering Information Part Name HD74AC280FPEL HD74AC280RPEL Package Type SOP-14 pin (JEITA) Package Code Package Abbreviation Taping Abbreviation (Quantity) FP-14DAV FP RP EL (2,000 pcs/reel) EL (2,500 pcs/reel) SOP-14 pin (JEDEC) FP-14DNV Notes: 1.
