The CD74HC4049 and CD74HC4050 are fabricated withhigh-speed silicon gate technology. They have a modifiedinput protecTIon structure that enables these parts to beused as logic level translators which convert high-level logicto a low-level logic while operaTIng off the low-level logicsupply. For example, 15-V input pulse levels can be downconvertedto 0-V to 5-V logic levels. The modified inputprotecTIon structure protects the input from negaTIveelectrostatic discharge. These parts also can be used assimple buffers or inverters without level translation. TheCD74HC4049 and CD74HC4050 are enhanced versions ofequivalent CMOS types.
