The ADS7864 has a 16-bit output word. DB15 is ‘1’ if
A0
0
the output contains valid data. This is important for
the FIFO mode. Valid Data can be read until DB15
A1

switches to 0. DB14, DB13 and DB12 store channel

information as indicated in Table 2 (Channel Truth

BYTE—If there is only an 8-bit bus available on a
board, then Byte can be set high (see Figure 29 and
Figure 30). In this case, the lower eight bits can be
read at the output pins DB7 to DB0 at the first RD
signal, and the higher bits after the second RD signal.
