DESCRIPTION:  
Microprocessor interfacing in serially controlled systems  
Buffered digital output pin for daisy-chaining multiple DACs  
Minimizes address-decoding in multiple DAC systems -  
three wire interface for any number of DACs  
- One data line  
Maxwell Technologies’ 8143 is a 12-bit serial-input daisy-chain  
CMOS digital-to-analog converter (DAC) that features serial  
data input and buffered serial data output and a greater than  
50 krad (Si) total dose tolerance, dependent upon space mis-  
sion. It was designed for multiple serial DAC systems, where  
serially daisy-chaining one DAC after another is greatly simpli-  
fied. The 8143 also minimizes address decoding lines  
enabling simpler logic interfacing. It allows three-wire interface  
for any number of DACs: one data line, one CLK line and one  
load line. Serial data in the input register (MSB first) is  
sequentially clocked out to the SRO pin as the new data word  
(MSB first) is simultaneously clocked in from the SRI pin. The  
strobe inputs are used to clock in/out data on the rising or fall-  
ing (user selected) strobe edges (STB , STB , STB , STB ).  
- One CLK line  
- One load line  
• Fast interface timing reduces timing design considerations  
while minimizing microprocessor wait states.  
Improved resistance to ESD  
• RAD-PAK® radiation-hardened against natural space  
radiation  
Total dose hardness:  
- > 50 Krad (Si), depending upon space mission  
• Package:

When the shift registers data has been updated, the new data  
word is transferred to the DAC register with use of LO1 and  
LD2 inputs.  
- 16 pin RAD-PAK® flat pack  
• Operating temperature: -40 to 85°C  
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.
