DESCRIPTION:

Maxwell Technologies’ 7545B is a 12-bit CMOS-buffered mul-

tiplying DAC with internal data latches, which features a

greater than 100 krad (Si) total dose tolerance, depending

upon space mission. The 754B features a WR pulse width of

100 ns which allows interfacing to a much wider range of fast

8-bit and 16-bit microprocessors. It is loaded by a single 12-bit

wide word under the control of the CS and WR inputs; tying

these control inputs low makes the input latches transparent

allowing unbuffered operation of the DAC. The 7545B is par-

ticularly suitable for single supply operations and applications

with wide temperature variations.

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 50

krad (Si) radiation dose tolerance. This product is available

with screening up to Class S.
