4000 Series Logic Gates, NexperiaThe HEF4081B is a quad 2-input AND gate. The outputs are fully buffered for highest noise immunity and pattern insensitivity to output impedance variations. It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.Key features and benefitsMixed 5 V and 3.3 V applicationsReduce time to market for complex designsSave board spaceOpen-drain output optionsImproved signal integrity for complex layoutsWide supply voltage rangeLow propagation delayOvervoltage tolerant optionsLow input threshold optionsCMOS low powerKey applicationsCell phoneComputingSTBLCD TVIndustrial controllers4000 CMOS Logic Family, NexperiaCMOS Family devicesWide operating voltage range: 3 to 18V
