SPECIFICATIONS 
ELECTRICAL CHARACTERISTICS—3.3 V OPERATION 
All typical specifications are at T
A
 = 25°C, V
DD1
 = V
DD2
 = 3.3 V. Minimum/maximum specifications apply over the entire recommended 
operating range of 3.0 V ≤ V
DD1
 ≤ 3.6 V, 3.0 V ≤ V
DD2
 ≤ 3.6 V, and −40°C ≤ T
A
 ≤ +125°C, unless otherwise noted. Switching specifications 
are tested with C
L
 = 15 pF, and CMOS signal levels, unless otherwise noted.
