Description

The 'HC4049 and 'HC4050 are fabricated with high-speedsilicon gate technology. They have amodified inputprotection structure that enables these parts to be usedaslogic level translators which convert high-level logic to a low.level logic while operating off the low-level logic supply. Forexample,15-vinput pulse levels can be down-converted to0-V to 5-V logic levels. The modified input protectionstructure protects the input from negative electrostaticdischarge. These parts also can be used as simple buffersor inverters without level translation. The HC4049 and'HC4050 are enhanced versions of equivalent CMOS types.
