I am trying to locate the technical specification for the H009 Data
Bus used in the F15 fighter. Can any one help?

MACAIR

    MACAIR is a nickname for a family of avionics databus
specification that came out of McDonnell Douglas for Navy aircraft.
These protocols are very similar to MIL-STD-1553 except that their
transmitted waveforms are controlled to look more like sine waves than
a trapezoid. The reason is that there are fewer high frequency
components in a rounded waveform, and therefore it reduces the
possibility of electromagnetic interference to sensitive aircraft
systems. Generally, MACAIR and MIL-STD-1553 terminals can communicate
with each other without difficulty. However, some purists chose to
replace a terminal's MIL-STD-1553 transceiver with a pin compatible
MACAIR version.

Were you looking for the signal waveform specifications?  If so,
Boeing (which bought McDonnell Douglas) would be the best source to
contact).
