Catalyst’s advanced CMOS technology substantially reduces device power requirements. The CAT24AC128 Features a 64-byte page write buffer. The device operates via the I2C bus serial interface and is available in 8-pin DIP, 8-pin SOIC or 14-pin TSSOP packages. Three device address inputs allows up to 8 devices to share a mon 2-wire I2C bus.
