The DDC316 provides two data output modes: time

In parallel output mode, as shown in Figure 10, four

division multiplexed (TDM) and parallel. In TDM

channels of data are output on the four DOUT lines,

mode, data from all 16 channels are output on a

DOUT1 thorough DOUT4.

single data output line, DOUT1, as shown in Figure 9.

In this mode, DOUT2 through DOUT4 are not used

In either mode, the most significant bit (MSB) is

and forced to logic low.
