According to my trusty hardware reference...

Pin 1:  A/D Input.  2.5 Vpp,  3000 ohm impedance
Pin 2:  Analog GND
Pin 3:  Analog Output   -5V to +5V,  10,000 ohm load minimum
Pin 4:  Channel Address bit 0   max 1 LS TTL load
Pin 5:  Channel Address bit 1
Pin 6:  Channel Strobe   goes LOW when address valid
Pin 7:  Channel Address bit 2


Hope this helps.   I've been planning on building my own little decoder
for this thing for a while now... might actually do it someday!
