D0–D7
Conversion data digital output pins. D0 is the LSB,
D7 is the MSB. Valid data is output just after the
rising edge of the CLK input. These pins are enabled
by bringing the OE pin low.

should have a
common supply and be separately bypassed with a
10 µF tantalum or aluminum electrolytic capacitor and
a 0.1 µF ceramic chip capacitor. See Section 3.0 for
more information.
