SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—3.3 V OPERATION
All typical specifications are at TA = 25°C, VDD1 = VDD2 = 3.3 V. Minimum and maximum specifications apply over the entire
recommended operation 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.
