During the transparent mode (CLK = LOW), any change of input data will be seen at the output. During the latched mode (CLK = HIGH), the analog

output remains stable regardless of any change at the input. A change of input data during the latched mode will be seen on the falling edge of the clock

(beginning of the transparent mode).
