3-2-10-2 Specifications
This section presents the electrical and environmental specifications of the PM-22.
1) Power Ratings
Table presents the PM-22’s minimum and maximum power ratings and storage temperatures.
* VDDBIAS is connected to the system’s 5.0V supply to provide 5V tolerance
on I/O signal pins (including all inputs, outputs, and bidirectionals). in systems
where 3.3V signaling only is used, connect VDDBIAS to a 3.3V supply.
2) Required Operation Conditions
Table presents the PM-22’s environmental specifications.
* VDDBIAS is connected to the system’s 5.0V supply to provide 5V tolerance
on I/O signal pins (including all inputs, outputs, and bidirectionals). in systems
where 3.3V signaling only is used, connect VDDBIAS to a 3.3V supply.
