ELECTRICAL CHARACTERISTICS—1.8 V OPERATION

All typical specifications are at TA = 25°C, VDDL1 = 1.8 V, VDD1 = 3.0 V, VDDL2 = 1.8 V, VDD2 = 3.0 V. Minimum/maximum specifications

apply over the entire recommended operation range: VDDL1 = 1.8 V, 3.0 V ≤ VDD1 ≤ 3.6 V, VDDL2 = 1.8 V, 3.0 V ≤ VDD2 ≤ 3.6 V,−40°C ≤ TA ≤

+125°C; unless otherwise noted. Switching specifications are tested with CL = 15 pF and CMOS signal levels, unless otherwise noted.
