NS9750B-A1 Datasheet 03/2006
Electrical characteristics
The NS9750B-A1 operates at a 1.5V core, with 3.3V I/O ring voltages.
Absolute maximum ratings
Permanent device damage can occur if the absolute maximum ratings are exceeded even for an
instant.
Recommended operating conditions
Recommended operating conditions specify voltage and temperature ranges over which a circuit’s
correct logic function is guaranteed. The specified DC electrical characteristics (see “DC electrical
characteristics” on page 42) are satisfied over these ranges.
