Data Sheet
ELECTRICAL CHARACTERISTICS—VDD1 = 3.3 V, VDD2 = 2.5 V OPERATION
All typical specifications are at TA = 25°C, VDD1 = 3.3 V, and VDD2 = 2.5 V. Minimum and maximum specifications apply over the entire
recommended operation range of 3.0 V ≤ VDD1 ≤ 3.6 V, 2.25 V ≤ VDD2 ≤ 2.75 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.
For dc specifications and ac specifications, see Table 3 for parameters related to Side 1 operation, and see Table 6 for parameters related to
Side 2 operation.

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