8143R5KL.25 - Brand New BI Technologies IC Chips
-
Description
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 mission. It was designed for multiple serial DAC systems, where serially daisy-chaining one DAC after another is greatly simplified. 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 falling (user selected) strobe edges (STB1, STB2, STB3, STB4). When the shift register’s data has been updated, the new data word is transferred to the DAC register with use of LO1 and LD2 inputs.
