The device’s cascadable feature allows up to eight devices to share a mon 2-wire bus. These device are optimized for use in many industrial and mercial applications where low-power and low-voltage operation are essential. Both devices are available in space-saving 8-lead SOIC, 8-lead TSSOP, 8-pad UDFN, 8-lead PDIP(1), 5-lead SOT23, and 8-ball VFBGA packages. The entire family of packages operates from 1.7V to 3.6V.
