High speed CMOS logic hex non-inverting buffers
RAD-PAK® radiation hardened against natural space radia-
tion
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 low-
level 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 electro-
static discharge. The 54HC4050 can be used as simple buff-
ers or inverters without level translation.

Maxwell Technologies' patented RAD-PAK® packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
age. 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 provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.
