CD4002MCD4002C Dual 4-Input NOR Gate

CD4012MCD4012C Dual 4-Input NAND Gate

General Description

These NOR and NAND gates are monolithic complementa-

ry MOS (CMOS) integrated circuits The N- and P-channel

enhancement mode transistors provide a symmetrical cir-

cuit with output swings essentially equal to the supply volt-

age This results in high noise immunity over a wide supply

voltage range No DC power other than that caused by leak-

age current is consumed during static conditions All inputs

are protected against static discharge and latching condi-

tions
