ELECTRICAL CHARACTERISTICS—2.5 V OPERATION

All typical specifications are at TA = 25°C, VDD1 = VDD2 = 2.5 V. Minimum/maximum specifications apply over the entire recommended

operating range of 2.25 V ≤ VDD1 ≤ 2.75 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.

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.
