own reference input, feedback resistor, and onboard data

latches that feature read/write capability. The readback func-

tion serves as memory for those systems requiring self-diag-

nostics.

A common 8-bit TTL/CMOS compatible input port is used to

load data into any of the four DAC data-latches. Control lines

DS1, DS2 and A/B determine which DAC will accept data.

Data loading is similar to that of a RAMs write cycle. Data can

be read back onto the same bus with control line R/W. The

8408 is a bus compatible with most 8-bit microprocessors,

including the 6800, 8080, 8085, and Z80. The 8408 operates

on a single +5 volt supply and dissipates less than 20 mW.

The 8408 is manufactured using highly stable, thin-film resis-

tors on an advanced oxide-isolated, silicon-gate, CMOS pro-

cess. The improved latch-up resistant design eliminates the

need for external protective Schottky diodes.

Maxwell Technologies' patented R

-P

® 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, R

-P

provides greater than 100

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

with screening up to Class S.
