The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The ATC0B/08B is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra-Thin Mini- MAP (MLP x), -lead SOT, 8-lead TSSOP, and 8-ball dbga packages and is accessed via a Two-wire serial interface. In addition, the ATC0B/08B is available in.8v (.8V to.v) version. Figure.
