5 V NOMINAL ELECTRICAL CHARACTERISTICS

Supply voltage (VSY) = 4.5 V, common-mode voltage (VCM) = VSY/2, TA = 25°C, unless otherwise specified. Typical specifications are equal to

the average of the distribution from characterization, unless otherwise noted. Minimum and maximum specifications are tested in production,

unless otherwise noted.
