The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. ELECTRICAL CHARACTERISTICS—2.5 V OPERATION All typical specifications are at TA = 25°C, VDD1 = VDD2 = 2.5 V. Minimum and maximum specifications apply over the entire recommended operation 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. Table 4.
