ELECTRICAL CHARACTERISTICS—V
DD1
 = 2.5 V, V
DD2
 = 3.3 V OPERATION 
All typical specifications are at T
A
 = 25°C, V
DD1
 = 2.5, and V
DD2
 = 3.3 V.
Minimum/maximum specifications apply over the entire 
recommended operating range of 2.25 V ≤ V
DD1
 ≤ 2.75 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. 
For dc specifications and ac specifications, see Table 6 for Side 1 and see Table 3 for Side 2.
