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/maximum specifications apply over the entire

recommended operating 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 Side 1 and see Table 6 for Side 2.

|tPLH − tPHL|

Within PWD limit

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.
