MM54HC280/MM74HC2809-Bit Odd/Even Parity Generator/CheckerGeneral DescripTIonThe MM54HC280/MM74HC280 uTIlizes advanced silicongateCMOS technology to achieve the high noise immunityand low power consumpTIon of standard CMOS integratedcircuits. It possesses the ability to drive 10 LS-TTL loads.This parity generator/checker features odd/even outputs tofacilitate operaTIon of either odd or even parity applications.The word length capability is easily expanded by cascadingdevices. The 54HC/74HC logic family is speed, function,and pinout compatible with the standard 54LS/74LS family.All inputs are protected from damage due to static dischargeby internal diode clamps to VCC and ground.FeaturesY Typical propagation delay: 28 nsY Wide power supply range: 2V±6VY Low quiescent current: 80 mA maximum (74HC)Y Low input current: 1 mA maximumY Fanout of 10 LS-TTL loads
