MM54HC266A/MM74HC266A Quad 2-InputExclusive NOR Gate (Open Drain)General DescripTIonThis exclusive NOR gate uTIlizes advanced silicon-gateCMOS technology to achieve operaTIng speeds similar toequivalent LS-TTL gates while maintaining the low powerconsumpTIon and high noise immunity characteristic of standardCMOS integrated circuits. These gates are fully bufferedand have a fanout of 10 LS-TTL loads. The MM54HC/MM74HC logic family is functionally as well as pin out compatiblewith the standard 54LS/74LS logic family. All inputsare protected from damage due to static discharge by internaldiode clamps to VCC and ground.FeaturesY Typical propagation delay: 9 nsY Wide operating voltage range: 2±6VY Low input current: 1 mA maximumY Low quiescent current: 20 mA maximum (74 Series)Y Output drive capability: 10 LS-TTL loadsY Open drain outputs
