Notes:
1. Current drain and power dissipation specs are based upon a small sampling of 3.3V transceivers and are subject to change.
2. Power dissipation is the input power minus the power delivered to the 1553 fault isolation resistors, the power delivered to the bus
termination resistors and the copper losses in the transceiver isolation transformer and the bus coupling transformer.
3. The thermal resistance numbers indicated are preliminary.
4. See Micro-ACE TE Data Sheet for current drain and power dissipation numbers for 5V only operation.
5. Power dissipation specifications assume a transformer coupled configuration with external dissipation (while transmitting) of 0.14 watts
for the active isolation transformer, 0.80 watts for the active bus coupling transformer, 0.45 watts for each of the two bus isolation resistors
and 0.15 watts for each of the two bus termination resistors.
