GT74LVC1G27

This single 3-input positive-NOR gate is designed for 1.65-V to 5.5-VVoc operation.

The GT74LVC1G27 device performs the Boolean functionY=A+B+C or Y=A·B·C in positive logic.The CMOsdevice has high output drive while maintaining low staticpower dissipation over a broadVoc operatingrange.

This device is fully specified for partial-power-downapplications using lot.The loff circuitry prevents damagingcurrent backflow through the device when the gate ispowered downandits output is floating
