VIx = VDDx1, VCM = 1000 V,
transient magnitude = 800 V
1 VDDx = VDD1 or VDD2.
2 |CM| is the maximum common-mode voltage slew rate that can be sustained while maintaining VOUT > 0.8 VDDx. 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.

|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.
