The device include a cascading feature that allows up to eight devices to share a common 2-wire bus. These devices are optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The AT24HC02C are available in space saving 8-lead PDIP, 8-lead JEDEC SOIC, and 8-lead TSSOP packages. In addition, the product operates from 1.7V to 5.5V V .
