DC characteristics

DC electrical specifications define the power supply voltages and currents, and the I/O voltage and drive characteristics.

Recommended operating conditions

The NS7520 operates using an internal core VDD supply voltage of 1.5V. A 3.3V supply 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.
