SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—3.3 V OPERATION
All typical specifications are at TA = 25°C, VDD1 = VDD2 = 3.3 V. Minimum/maximum specifications apply over the entire recommended
operating range of 3.0 V ≤ VDD1 ≤ 3.6 V, 3.0 V ≤ VDD2 ≤ 3.6 V, and −40°C ≤ TA ≤ +125°C, unless otherwise noted. Switching specifications
are tested with CL = 15 pF, and CMOS signal levels, unless otherwise noted.

1 tPSK is the magnitude of the worst-case difference in tPHL and tPLH that is measured between units at the same operating temperature, supply voltages, and output load within the
recommended operating conditions.
