For each of the parallel DME tuning discrete outputs:
INACTIVE: Floating (can be pulled up to externally sourced Vout in the range 0
≤  Vout ≤  33VDC)
Leakage current in the INACTIVE state is typically ≤ 10 uA to ground
ACTIVE: Vout ≤ 0.5VDC with ≤  20 mA sink current
Sink current must be externally limited to 20 mA max
NAV DME COMMON must be pulled low to indicate to the NAV module that it is the device channeling
the DME.
INACTIVE: 10
≤  Vin ≤  33VDC or Rin ≥ 100k Ω
ACTIVE: Vin ≤ 1.9VDC with ≥  75 uA sink current, or Rin ≤ 375 Ω
Sink current is internally limited to 200 uA max for a grounded input
