ELECTRICAL CHARACTERISTICS—1.8 V OPERATION

All typical specifications are at TA = 25°C, VDD1 = VDD2 = 1.8 V. Minimum/maximum specifications apply over the entire recommended

operation range: 1.7 V ≤ VDD1 ≤ 1.9 V, 1.7 V ≤ VDD2 ≤ 1.9 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. Supply currents are specified with 50% duty cycle signals.
