These parts have a modified input protection structure that enables them to be used as logic level translators which will convert high-level logic to a low-level logic while operating off the lowlevel logic supply. For example, 15V input pulse levels can be down-converted to 0V to 5V logic levels. The modified input protection structure protects the input from negative electrostatic discharge. The 54HC4050 can be used as simple buffers or inverters without level translation. Maxwell Technologies' patented RAD-PAK® packaging technology...
