DC characteristics and other operating specifications

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

for the I/O cells, which drive/accept 3.3V levels.

Table 4 provides the DC characteristics for inputs; Table 5 provides the DC characteristics for

outputs.

Table 6 defines the DC operating (thermal) conditions for the NS7520. Operating the NS7520 outside

these conditions results in unpredictable behavior.
