SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—5 V OPERATION
All typical specifications are at T A = 25°C, V DD1 = V DD2 = 5 V. Minimum/maximum specifications apply over the entire recommended
operation range of 4.5 V ≤ V DD1 ≤ 5.5 V, 4.5 V ≤ V DD2 ≤ 5.5 V, and ?40°C ≤ T A ≤ 105°C, unless otherwise noted. Switching specifications
are tested with C L = 15 pF and CMOS signal levels, unless otherwise noted.
