Note that CS and CLK are combined with an OR gate and  
the output controls the serial-to-parallel shift register inter-  
nal to the DAC7614 (see the block diagram on the front of  
this data sheet). These two inputs are completely inter-  
changeable. In addition, care must be taken with the state of  
CLK when CS rises at the end of a serial transfer. If CLK is  
LOW when CS rises, the OR gate will provide a rising edge  
to the shift register, shifting the internal data one additional  
bit. The result will be incorrect data and possible selection of  
the wrong DAC.

NOTES: (1) L = Logic LOW. (2) X = Don’t Care. (3) Resets to either 000H or  
800H, per the RESETSEL state (LOW = 000H, HIGH = 800H). When RESET  
rises, all registers that are in their latched state retain the reset value.  
If both CS and CLK are used, then CS should rise only when  
CLK is HIGH. If not, then either CS or CLK can be used to  
operate the shift register. See Table III for more information.

where N is the digital input code (in decimal). This equation

(full-scale) errors.

NOTES: (1) CS and CLK are interchangeable. (2) H = Logic HIGH. (3) X =  
Don’t Care. (4) L = Logic LOW (5) = Positive Logic Transition. (6) A HIGH  
value is suggested in order to avoid a “false clock” from advancing the shift  
register and changing the shift register. (7) If data is clocked into the serial  
register while LOADDACS is LOW, the selected DAC register will change as  
the shift register bits “flow” through A1 and A0. This will corrupt the data in  
each DAC register that has been erroneously selected. (8) RESET LOW  
causes no change in the contents of the serial shift register.
