The device is compatible with Fast-mode I2C bus specification and operates down to 1.8V with a bit rate up to 400 kbit/s. Extended addressing capability allows up to 8 devices to share the same bus. Catalyst's advanced CMOS technology substantially reduces device power * Catalyst Semiconductor is licensed by Philips Corporation to carry the I2C Bus Protocol. requirements. The device is optimized for high performance applications, where low power, low voltage and high speed operation are required. CAT24FC32A is available in 8-pin DIP, 8-pin SOIC (JEDEC and EIAJ) and 8-pin TSSOP packages.
