ELECTRICAL CHARACTERISTICS—2.5 V OPERATION
All typical specifications are at T
A
= 25°C, V
DD1
= V
DD2
= 2.5 V. Minimum/maximum specifications apply over the entire recommended
operating range of 2.25 V ≤ V
DD1
≤ 2.75 V, 2.25 V ≤ V
DD2
≤ 2.75 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.
