ELECTRICAL CHARACTERISTICS

Typical (Typ) values are given for VS = 1.8 V and TA = 25°C, unless otherwise noted. Minimum (Min) and maximum (Max) values are given over

the full VS = 1.8 V ± 5% and TA = −40°C to +85°C variation, unless otherwise noted. Input slew rate > 1 V/ns, unless otherwise noted.
