DC characteristics
DC electrical specifications define the power supply voltages and currents, and the
I/O voltage and drive characteristics.
The NS7520 operates using an internal core V
is required for the I/O cells, which drive/accept 3.3V levels.
This table defines the DC operating (thermal) conditions for the NS7520. Operating
the NS7520 outside these conditions results in unpredictable behavior.
