Part Description: 74F280 9-Bit Parity Generator Checker

Part Details:

74F280 9-Bi April 1988 Revised September 2000 t Pari 74F2809-Bit Parity Generator/Checker ty Generat General DescriptionThe F280 is a high-speed parity generator/checker thataccepts nine bits of input data and detects whether aneven or an odd number of these inputs is HIGH. If an evennumber of inputs is HIGH, the Sum Even output is HIGH. If o an odd number is HIGH, the Sum Even output is LOW. The r/ Sum Odd output is the complement of the Sum Even out- Checker put.
