High-Speed CMOS Logic Hex Buffers, Inverting and Non-Inverting
Description
The ’HC4049 and ’HC4050 are fabricated with high-speed silicon gate technology. They have a modied input protection structure that enables these parts to be usedas logic level translators which convert high-level logic to a lowlevel logic while operating off the low-level logic supply. For example, 15-V input pulse levels can be down-converted to 0-V to 5-V logic levels. The modied input protection structure protects the input from negative electrostatic discharge. These parts also can be used as simple buffers or inverters without level translation. The ’HC4049 and ’HC4050 are enhanced versions of equivalent CMOS types.
