The NS7520 operates using an internal core V
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 4: DC characteristics — Inputs
Table 5: DC characteristics — Outputs
Table 6 defines the DC operating (thermal) conditions for the NS7520. Operating the NS7520 outside
these conditions results in unpredictable behavior.
