54HC4050

Maxwell Technologies' 54HC4050 high speed CMOS Logic Hex Non-Inverting Buffers features a greater than 100 krad(Si) total dose tolerance, depending upon space mission. 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 of 54HC4050 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 of 54HC4050 incorporates radiation shielding in the microcircuit package. It eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or space mission. In a GEO orbit, RAD-PAK of 54HC4050 provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up to Class S.
