... CAT514’s Tri-Stated Data Output pin. A Rdy/Bsy output working in concert with an internal low voltage detector signals proper operation of EEPROM Erase/Write cycle. The CAT514 is available in the Commercial and – Industrial operating temperature ranges and offered in 14-pin plastic DIP and SOIC packages. ...

... CLOCK The CAT514’s clock controls both data flow in and out of the IC and EEPROM memory cell programming. Serial data is shifted into the DI pin and out of the DO pin on the clock’s rising edge. While it is not necessary for the clock ...

... DATA OUTPUT Data is output serially by the CAT514, LSB first, via the Data Out (DO) pin following the reception of a start bit and two address bits by the Data Input (DI). becomes active whenever CS goes high and resumes its high impedance Tri-State mode when CS returns low ...

... EEPROM then a change would occur at the read cycle’s conclusion. TEMPORARILY CHANGE OUTPUT The CAT514 allows temporary changes in DAC’s output to be made without disturbing the settings retained in EEPROM memory. This feature is particularly useful when testing for a new output setting and allows for user adjustment of preset or default values without losing the original factory settings ...
