• ESD protection exceeds 2000 V
DESCRIPTION:
Maxwell Technologies’ 54BCT244 octal buffers and line driv-
ers features a greater than 100 krad (Si) total dose tolerance;
depending upon space misssion. The 54BCT244 is organized
as two 4-bit drivers with separate output enable (OE) inputs.
When OE is low, the device passes data from the A inputs to
the Y outputs. When OE is high, the outputs are in the high
impedance state.
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 a space
mission. In a GEO orbit, RAD-PAK provides true greater than
100 krad (Si) total radiation dose tolerance, dependent upon
space mission. This product is available with packaging and
screening up to Class S.
